Radiation in Helium   As quoted in your description of Helium you stateOn Earth helium is primarily a product of the radioactive decay of much heavier elements which emit helium nuclei called alpha particles it is found in significant amounts only in natural gas from which it is extracted at low temperatures by fractional distillation I have a question on that subject Does Helium retain any Radiation after processing As a deep sea diver we breath up to  Helium at deeper depths in saturation diving and our cells get saturated with the element I would like any info on this matter that you can supply   Thank you
