These long embedded viral codes from times past in human evolution, close to monkeys, encoded this into our human genes. Hence, the HIV was associated early on with being transmitted from monkeys to humans. Low level radiation also affects the human stem cells DNA and affects the antibody and human T-cell genetic processes, as well as the immune systems tolerance. This is an unthinkable act of pure neglect or human experimentation that allows these workers to be exposed to these sources. It is more along the lines of using them as human guinea pigs to study the effects of long term low level neutron exposures.
Neutrons are many times more health harming than any other radiations.
Neutrons also activate the things they hit as the neutrons are absorbed by nearby atoms. This simply stated is a crime. Violations of 10CFR20.1101 and 10CFR20.1003. Neutrons also exist in the K-25 depleated uranium or tailings yards due to the alpha bombardment of flourine atoms releasing neutrons. Neutrons in air can also make Carbon-14, due to activation of nitrogen in the air, another isotope that can cause health problems at long range.
