Well, as long as they don’t eat it or snort it, they should generally be fine, as well.
I mean, this guy (and several others) were injected with Pu-238. He lived another 20 years or so and died of heart disease. None of the people injected with plutonium in this nutso experiment died of it.
Eating it would not be much of a problem. Plutonium is absorbed into the body very poorly from the digestive system. The idea that plutonium is an extremely dangerous toxin is a myth, largely perpetrated by Ralph Nader. Dr. Bernard Cohen once famously challenged Nader by offering to eat a certain amount of plutonium if Nader would eat an equivalent mass of caffeine. Nader wisely declined, as caffeine is far more poisonous than plutonium.
I can buy that, if you eat it, it relatively quickly just passes through. But I’d have thought that an injection would be lethal in fairly short order.
If it will charge to 121 GW instead of 1.21 GW, it is better. Capacitors store charge, they do not require a level of charge to operate. It stores Coulombs, not power measured in Watts.
