An overdose of gamma rays is like a vicious sunburn, with skin damage and elevated cancer risks, but those particles are too big to penetrate our skin, meaning that they need to be swallowed or inhaled to wreak damage. The truly fearful event in a nuclear accident, then, isnt fallout but meltdown, where the core burns through the floor and suffuses the water table. There it causes agricultural havoc and radioactive dust that you better not breathe. Were not dropping dead all together from radiation poisoning or its ensuing cancers on a daily basis because, like all poisons, it isnt the particular atom that will get you. Its the dose. And damage from radioactivity requires a much greater dose than any of us would have believed. |
