A person being exposed to radiation (restricted to gamma) can have a time dependent effects. One can die in a year, months, or even days depending on the dose. Is it possible that gammas can kill a person almost instantly?
http://www.wise-uranium.org/eftokc.htmlOn September 30, 1999, a criticality accident occured at the Tokai nuclear fuel plant (JCO Co. Ltd., a 100% subsidiary of Sumitomo Metal Mining Co. Ltd.) in Japan. . . . The chain reaction caused heavy releases of gamma and neutron radiation. Three workers were exposed to doses of up to 17 Sv (Sieverts), causing severe radiation sickness. The worker exposed to the higest dose died on December 21, 1999. The worker exposed to the second highest dose of 6 - 10 Sv died on April 27, 2000. 68 other persons were irradiated at lower levels. Among them were the workers who stopped the chain reaction: they were exposed to doses of up to 119.79 mSv, exceeding the 100 mSv limit for emergency situations. The annual dose limit for workers is 50 mSv (while ICRP currently recommends 20 mSv). As of October 7, 1999, radiation levels remained high inside the plant building, preventing inspection of the damage inside the plant.
I find the claim that Russia gave the Vietnamese ray guns difficult to credit.
The energy in absorbed radiation ultimately ends up as heat, and we know enough heat kills cells. So yes, it's possible to absorb enough radiation to die immediately. However, this is many orders of magnitude more than LD50, so anyone using these putative ray guns would be in danger of dying themselves from backscattered radiation.[/QUOT
It's correct that radiation cause heat. However, I don't think that's the case. If you cook, that's no different than conventional fire. I believe it's through the ionizing mechanism. Radiation can be block using water, lead, poly... only need 2 inches of lead to reduce it to 1/10.
I still don't find the claim that Russians are passing out ray guns credible.
Given that, it seems...um...premature to try and figure out how they work.
The "Geneva rule"? You mean the Geneva Convention? Of 1949? Nothing about rayguns in that, I'm afraid. But in any event, this conversation has moved from the scientific, past the speculative and is rapidly approaching the silly.
well, whatever rule that is. The world must come together at some point. I don't know what's your concern here. You do not believe such a weapon exist or you do not believe Russians give out such weapon. It doesn't matter, my question is already answer. Thx.
