I like to make up theories about these thing. Anti-radiation is as stated, every particle of radiation has an equal and opposite particle, that cancels out the existence of radiation. So I’d be interested in testing out the nuclear fallout shelter I’ve built, out of residual material from fires (charcoal, fired soil, ash) along with corresponding animals (fighting chickens, koi, goldfish) to diffuse impact. I have made up a lot of anti rad devices out of fire residual, rocks, sand, dirt. I’d honestly be down to apply radioactive material, to see if it works. Meaning I’d finish my workout… I have burnt uranium, it did hurt me once or twice, but I wasn’t sure if it was chemically or from radiation? If there is such things as anti-rad, I would apply radiation to epicenter of it, to spread anti rad by suppression thus evolution, may stop nuclear fallout radiating centers for anti-rad specifically.
