The radioactive radiation radiation of radioactive radicals is called radiation. 'Radioactive ray' or a high-power electromagnetic radiated force. Equilibrium of neutron and proton in the nucleus of the atom of each element is equal. The elements of atomic atoms which are more than the ones (usually over 200 or above) are called heavy elements. The alpha, beta, and gamma rays emanate from the nucleus of these huge basic materials, this process is called radio-activity.

Source of radioactivity

The source of radioactivity can be divided into three categories: natural, human, and surrounded by environmental.

1. Natural Source - All the Earth's nucleus of electrons, protons and a few atoms from the surface are struck by light almost at the speed of the earth. These are called cosmic rays. These rays are electrically charged. Natural radioactivity moves into the surface of the atmosphere by spreading a small amount of atmosphere. The higher the height of the surface of the surface than the sea level, the greater the level of its growth. Radon Gas is the most important source of natural resources. It is 8 times heavier than the wind. It has three natural isotopes. These are caused by radioactivity of radium, uranium and thorium. Apart from natural rock, plants, animals and various industries, radian gas is added to the atmosphere.

2. Man-made - The level of radioactivity created by humans is varied according to space and time. X-ray (Ranzan) and other radiation therapy machines are a significant source of radioactivity. Various components are used to increase the production and quality of industries in the industrial sector, from which dangerous holes are created. Nuclear reactor, nuclear weapons testing and nuclear power plants, and the large number of radioactive substances spread over large areas in the surrounding areas.

3. The surrounding environment - almost every thing around us is being radiated. Our homes, food, drinks, even radiating radioactive rays from our own body. This radiation is very low, which is not harmful to humans. Based on the surrounding environment, its rate may be more or less. As the brick-built house radiation levels are more than the wooden house.

Risk of radioactivity

Not all tactical substances react to the same. If excessive radioactive substances enter the body or come in touch then we may face different types of physical and mental problems. The reason being that it is harmful to humans is that radioactive ray emitted from the root due to radioactivity is afraid to destroy the living cells of the body when it comes to human contact; Because alpha and beta rays create burn conditions in the skin and gamma ray acts on the formation of cells. High levels of radiation radiation can lead to various cancers in the human body. If the exposure to excessive radioactive radiation for a long time reduces the immune system, mental illness or disability can also occur. The harmful effects of the disease are seen throughout the region.

There are 4 steps to the problems caused by radiation levels,

• First Step ...
  Receiving radiation from the body up to 25 meters will cause any reaction - not because it is tolerable;
• Second step ...
  If radiation from 25 to 100 is observed, then some reactions to blood and cells can be noticed, but it occurs in a long time and there is no serious reaction;
• Step Three ...
  Physical symptoms range from 100 rms to 300; Such as physical and nervous weakness, vomiting, weak headache, reducing the amount of white blood cells in the blood. In this case must be taken care of; Due to the right and timely good treatment, the problem is usually-no;
• Fourth step ...
  If the level is more than 300 mm, then the final loss may occur - in the death-weight (450-meter). The symptoms are: hair fall, skin swirling, black spots in the skin, deadly deterioration of cells etc. If there is no timely treatment, such patients will die within 2 to 14 days.

Use of radioactivity

In today's world, radioactivity is being used in different areas of action,

1. Generating electricity:
   Electricity production through nuclear power is the biggest and most significant contributor to this energy. By generating heat energy from the heat excretion process from the tissue isotope, electricity is produced through turbines and generators.
2. Medical case
   X-ray, fluoroscopy, CT scan, memography, sister dentatometer, angiography, etc. Cell division - it plays an important role in the treatment of various diseases (such as cancer). Radioactive treatment is used to cure cancer diseases. Cancer treatment is done by killing gamma ray with cancer cells in radiotherapy. Various types of different types of radio isotope are used in early detection and also for the treatment of certain diseases; In particular, diagnosis and treatment of various types of thyroid cancer including cancer of the thyroid.
3. Medicines:
   In 80 percent of cases, radioactive materials are used to test drug-free sterilization and efficacy. Radioactive materials are used in biomedical research, including the management of AIDS, cancer, Alzheimer's disease and disease-related research.
4. Industry:
   The speed of liquid or gaseous substances operated through pipelines, filtering efficiency, and the internal deterioration rate of pipelines using very little amount of radioactive material; Determining the level of fluid or powdered material in a container or vessel; To determine the exact amount of thickness, density and material of various objects in the production or production industry; With polymers, it is widely used in the development of various types of materials by applying radioactive technology. In clock clocks, the zygote sulfide mixed with the radioactive thorium is plated in the clockwise and the number is shrouded in the dark, so that they are shaded in the dark. In construction or paper, plastic, aluminum, Determine the exact amount of thickness, density and element of the object Alpha and beta rays are used e.
5. In case of agriculture:
   Radioactive rays are used to improve food quality, conserve, increase nutrients and reduce pest. With the introduction of radioactive radiation by genetically altering the crop, it is possible to produce more yielding, adversarial and pest attack resistant crops. Research on the development of improved seeds is used successfully in radioactivity.
6. In the environment:
   By using radioactive material in small quantities, it can be possible to determine the main, aromatic or superficial elements in soil, water or air, due to the presence of pollutants in the air and soil, soil surface or surface water, or presence of harmful substances arsenic, lead, cadmium or other harmful substances for human health. diterminate; In the case of dam and irrigation, it is possible to measure the rate of flow of rivers, drainage of water and the rate of increase in the amount of garbage or drainage.
7. Water Management:
   Determination of location of geological water through geological and chemistry analysis in the method of isotope hydrology, specifications of its location, age, age, determination of properties of pollution in the water, and determination of quality; Detection and distribution of new and renewable water sources; The use of water recycling in deep and shallow water reservoirs and the interaction between them is analyzed and analyzed.
8. In Space:
   Radioactive isotopes are used as sources of energy in submarines and non-human space.
9. In case of geological / anthropological / archaeological research:
   It is possible to determine the age of fossil samples and rocks by analyzing the carbon dating method, in order to prove the authenticity of various types of research, museum paintings or other works of art, including the idea of ​​evolution, by analyzing the internal chemical and biological processes of plants, in the exploration and development of mineral resources, Minerals Physical and Chemical It is used for analysis of properties. The fossil samples and age of the rock are analyzed by analyzing the carbon dating method (radiation-measuring measurement).
10. Housekeeping:
    For the lasting preservation of those materials which have the potential to be lost in the heat application, in order to increase the memory of computer disks, smoke detectors, to test whether the nonstick pan was used properly for cooking, photocopies are used in photocopying machines, Photocopy The machines are stuck together in the paper so that the machine is not damaged The second is that the radioactive material, etc., are used.
11. For safety:
    X-ray machines, scanning machines, and smoke detectors, neutron sources, etc. for scanning security provisions.
12. The radioactive isotope of these metals is widely used as radioactive displays to determine the amount of metals in the minerals.
13. These radiation is being used to make nuclear weapons.

#Wi-Fi Radiation:
WiFi, Bluetooth, and wireless technology are much more in the present era. Wireless router or WiFi modem is a kind of electromagnetic radiation that allows us to receive signals on our computers. Various types of wifi or wireless router or routing technology are used in our home or office, from which the terrible electromagnetic radiation stops. Researchers at Wageenigen University said that radiation emitted from Wi-Fi networks could be the reason for the death of large trees. Tree branches and leaf fall out when planting trees near the wireless writer. Radiation emitted from Wi-Fi can affect people's body not only from trees. Researchers say that the leafy leaves of the Wi-Fi network source have a kind of glittering plaque on the leaves. Radiation causes the leaves of trees to die, thus decreasing the growth of trees. Wireless is responsible for the local area network. In the Netherlands, 70 percent of the trees were found to have radiation problems.

Some wireless modems and transmitters of radio signals in that frequency are equivalent to heating or cooking frequencies in a microwave oven. When you search the WiFi network from your mobile or PC, the surrounding WiFi signal shows. But how does it show? When you or your neighbors search the wave while creating a wave, the electromagnetic field produces around it, which produces electromagnetic radiation. In this way, these waves can penetrate your body and cause different cancers and skin cancer. Here's a good wireless router, as much as you would have, the higher the radiation level and the higher the radiation level you will be, and you will be more likely to be physically and mentally at risk.

Mobile Phone Radiation:

Finnish scientist Davis claims that due to radiation, mobile phones in the book pocket have an impact on the heart. He highlighted the damage to radiation around the world, in his book Disconnect, 'The Truth About Cellphone Radiation'. Ultraviolet ray effect is long-term. As a result, people can not understand immediately. When the children speak for a minute on a mobile phone, the vibration that is made in the bree, it takes two hours to set the vibration. In the electromagnetic radiation, people can face premature aging. They will suffer from visual impairment and various diarrhea. Cancer, brain cancer, asthma, tumors, brain tumor, blood cancer, and many other complex diseases such as viscosity. There is a variety of diseases, including kidney disease, ear acupuncture, reduced hearing loss, blood circulation obstruction, chest pain, skin diseases, cancer, heart attack, eye problems, and brain disabilities. If the pocket pocket of the mobile is reduced, the reproductive capacity of the male decreases, The weak, the sperm decreases. Such harmful waves can affect sperm and reduce sperm density. It is the most serious of the pregnant women. One in every 4 children in touch with mobile phones has a health risk. Mobile radiation causes chronic tumor. Dr. Pran Golap Dutta says, every 15 minutes continuously increases the head temperature by 1 degree and increases 20 minutes to 2 degrees. Because of which there may be problems in the ears and in the brain.

Bin Khurana, an unbanked Indian cancer specialist, has long claimed that mobile phones are harmful than smoking. According to the World Health Organization, mobile phone radiation may be up to cancer. Excessive mobile consumption is likely to cause body damage. Because of long-term speech, ear problems, wrinkles in the ears, pain in the ear, damage to the brain neuron, pains, perkinsons, brencose can become weak. Most mobile phone users have already started to suffer from these diseases. As a result of mobile usage, countless children of the country are now being affected by 'autism' (mental retardation). Another aspect of the problem is that even when we do not talk on the phone, the radiation continues to harm us. If the mobile is on, the electromagnetic wave is coming from the tower. Talking about the phone in the ear, it comes close to the brain. The radiation flows through the body.

Mobile Tower Radiation:

Mobile Tower Radiation is a silent killer's name. Scientists say it is more horrific and intense than global warming. Living near the mobile tower and its powerful antenna is harmful. Ultraviolet ray emitted from the tower causes fatalities on human cells. The cell distortion occurs when the electrons magnetization radiation is produced separately in the body. Long-term harmful effects are falling. Due to mobile tower radiation, fatal diseases, including tumor, Alzheimer's, brain tumor, cancer, infertility, sleep apnea, high blood pressure, cardiovascular disease and abortion, have increased unexpectedly. Also, its radiation can penetrate our brain and cause serious damage to the DNA breakdown. Disease reactions and chromosomal deficiency symptoms appear in the body after radiation. Cells of the body of the nerve can be lost and people may suffer from acute disorders of Parkinson's, Alzheimer's, etc. As a result, a disabled, unmanageable and inefficient generation can be created in future in the country. The external symptoms of these diseases are slow-wounding, headaches, decreased digestibility, increased heart rate, depression, depression, fear of unnecessary and lacking in work, loss of memory and forgetting. According to experts, The towers have been installed in nearby, nowadays due to its radiation, children of nowadays may suffer from chronic diseases.

Mobile towers in developed countries are located far from educational institutions, hospitals and residential areas. But in the picture of Bangladesh, the economy of agriculture depends on the opposite. Negative effects of mobile tower radiation In the near future crop production, food security can lead to severe catastrophes in life and livelihood. According to electrical experts, the connectivity of towers from mobile towers in Bangladesh is through the megnet It has a relation with the thunder of the sky. Because of which, many people are dying in recent lightning. Mobile towers cause genetic changes in biodiversity. There are serious negative effects on the environment. The trees surrounding the tower are being victimized by the disease or the yield is less. The soil biological power is also wasting. Due to the radiation of the tower, there is widespread damage to animals and animals. According to a survey, due to the effect of the EMR of the mobile tower, due to the decline in coconut production in cemented celestial trees, in the absence of premature water, most of the dabi-coconut water, small in size, and many trees in the early morning.

Electro Magnification Radiation (EMR) emitted from the mobile tower is so severe that it is harmful to animals, birds, insects and even human biological systems in many ways. A study in the United States found that the number of bees in the last few years has decreased significantly. Because of which, increased pollution of electromagnetic radiation (EM) has been blamed. Ants on research showed that the open ants on the EMR lost their scent, sight and memory within a few hours (Kemert, 2012). Alfosona balmori (in 2005) proved that the effect of emra reduces the abrasion, wing, and movement of spiders, doves, storks, dowels and other species of birds and leaves. A study in Russia showed that 75 percent of the open chicken pox in the GSM phone was destroyed by the fall of the egg and birds left their homes in a week from the bird's nest in the mobile tower and the egg from the baby puseta. Paraguopulas and Margarithis scientists have shown that up to 50 percent of the open fruit fat near the digital GSM phone reduces breeding capacity. If the male and female insects are kept open in radiation for 6 minutes each day, 50 percent reproduction capacity will decrease in 4-5 days. Alfosona Balmori - In the first half of 2006, a link to the erosion of frogs by microwave radiation was first mentioned in an article. Improper mobility, inconsistency and high mortality (90%) can cause IMR. It has been published in the US media that under the influence of the EMR the fish and the batons are dying dramatically. Milk cow milk production decreases, spontaneous abnormalities with spontaneous abortion and severe reproduction. Thirty-two percent of the cow standing next to the mobile tower is suffering from cataracts (smile, 2012). The IMR is responsible for generating heat. As a result, insects and microbes living in the soil die. Which can bring catastrophic disaster. Bacillus subtilis, Mycobacterium was destroyed by radiation effects (Virk and Fogerty, 1967). During the Sugar Farmation E.M.R. The breeding of coli is hampered, especially the number of living cells decreases. Various negative effects of electrical magnetic radiation in plants, crops and vegetables have already been proven.

Electronic Waste Radiation:

The impact of electronic waste is even worse. The battery used on mobile phones is causing harmful chemical reactions. Electronic waste (e-waste) contains harmful substances such as radiation, lead, mercury, cadmium, bromine, retardant foam and polyvinyl chloride. It is toxic to the environment. Human health is also facing a serious risk. People are being attacked by various complex diseases including cancer and tuberculosis. E-waste (e-waste) is a waste of old computer, laptop, mobile phone, tube light, charger, television, refrigerator, fax machine, electric bulb. Wherever they leave them, the poison spreads in the environment. That makes water-air and weather toxic. E-waste soil nutrients-fertile energy is damaged. Do not result in crops. The tree does not bear fruit. The poisonous substances in the human body are being transported through crops and water. The World Health Organization says people who are exposed to e-waste are affected by kidney diseases, cancer, hearing loss, asthma, neurological weakness, lung damage, asthma, TB (tuberculosis), brain disorders, and many other complex diseases. Apart from this, many problems including insomnia, decrease of memory and dermatitis can occur in the human body. Most of the old and cheap priced computer-mobile phones are coming out. These waste contain carbon-toxic-harmful substances. Which is mixed with soil and water polluting crops and the environment. Creating a deadly harmful condition of people

Radiation on computers:

Computer experts said that the body tissues were damaged in front of the computer for more than 8 hours continuously. To cause many diseases. The computer can be called a light source. So looking at this light continuously, it is normal to have eye problems Those who play more games can cause a lot of damage to their eyes. According to the National Radiation Prevention Council of the United States, if this radiation continues for a long time, the brain may be infected, the normal function of the hormone may be hampered, which can lead to cancer by infecting various cells in the body. Those who browse the internet, they must know that the next day, there are many symptoms of eye irritation, starting from water, because one monitor. The computer should not be used for pregnant people. Scientists have researched that those who used more than 20 hours of pregnancy have been Micrariases, Pre-Mature and Still-born babies. This is for computer's electromagnetic radiance. When pregnant women use computers, they are stressed on the pregnancy.

Electro Magnetic Radiation:

Our constant computer, television, and power lines all spread dangerous electromagnetic radiation. Those who work on computers for a long time have many more difficulties with depression, allergy. For these, the scientists blamed the electro-magnetic radiation. This electro magnetic radiation has spread across the country through mobile phones, computers, internet, television, and electricity lines. This invasive killer electromagnetic radiation has triggered a horrendous health risk in countries such as 'Slow Poison'. All of the people and animals are at risk of this death. 90 percent of the mobile tower of the country is located in the roofs of the localities, buildings and educational institutions, the risk has increased hundreds of times. TV-radio towers also spread radiation

To do self-defense from radioactivity:

Staying out of keen sunscreen (12-2pm noon). Try to avoid rainwater as much as possible. Consume food rich in chlorophyll and oxidant. Use iodine in food (iodized salt). Use sun-glass when you go out of the day. Do not take too many radiation therapy over. Stay away from all the machines that are X-ray and radiation. When you go out outside the day, use body cover or sun-lotion or cream. Awareness of the side effects of the chemicals used in household chores in daily life. Use the radiation detection device at laboratory and industrial factory workplace. Try mixing the chemicals that are artificially mixed and marketed.

Due to radiation due to any symptoms of radiation sickness, patients should be removed from radioactive areas as soon as possible. Changing the clothes will reduce radiation. As soon as possible the patient should be taken to the hospital. Although radioactivity can not be completely avoided, but if we take a few warnings, we can reduce its levels very much. Awareness and remedies needing treatment before all radiation seeps with cancer.
