ECCO - Testing for 'strange radiation'

Before giving us a large sample of ECCO 'fuel', Suhas Ralkar wanted to warn us about a curious property it has, it likes to destroy the Polyethylene (PET) bottle he was about to supply it in. He took another sample from the shelf and held it aloft and just with a slight pressure from his fingers, the whole thing exploded!

Strange radiation

Could this degredation of the polymer not come simply from a chemical process, but additionally from the prior influence of strange radiation?

You can see here that PET is resistant to a wide range of chemicals, including, for instance, concentrated potassium hydroxide.

We appear to have observed tracks that look like strange radiation, which was reported here.

Indeed, there are links in that previous article where other scientists have used a polymer, called CR-39, to detect the strange radiation.

In the radiation detection application, CR-39 is used as a Solid-State Nuclear Track Detector to detect the presence of ionising radiation. Energetic particles colliding with the polymer structure leave a trail of broken chemical bonds within the CR-39. When immersed in a concentrated alkali solution (typically sodium hydroxide) hydroxide ions attack and break the polymer structure, etching away the bulk of the plastic at a nominally fixed rate. However, along the paths of damage left by charged particle interaction the concentration of radiation damage allows the chemical agent to attack the polymer more rapidly than it does in the bulk, revealing the paths of the charged particle ion tracks. The resulting etched plastic therefore contains a permanent record of not only the location of the radiation on the plastic but also gives spectroscopic information about the source. Principally used for the detection of alpha radiation emitting radionuclides (especially radon gas), the radiation-sensitivity properties of CR39 are also used for proton and neutron dosimetry and historically cosmic ray investigations. SOURCE

What could be happening therefore, is that the strange radiation is making the PET chemical bonds break down a little, therefore making it vulnerable to etching by the Potassium Hydroxide.

The experiment

So, the experiment would start with exposing PET to the 'strange radiation' from the fuel without making direct contact with it and then immersing that exposed PET, into Potassium Hydroxide to see if there is any etching effects.

Some PET taken from the same bottle but not exposed to the fuel, in any way, would be used as a control.

Update 1

Amongst other things, in this video, preventing exposure to UV radiation and deliberately adding it is discussed, also ways to test if any potential 'strange radiation' or its effects can be guided. Updates have been made including some in response to recent requests by contributor Martijn Lammers and historical comments by 'Axil Axil'.

Update 2

First thermal neutron, continued degradation of the sample bottle.
