RE: AW: AW: Green glowing powder emitting gammas
Yes, I know :) However, Bremsstrahlung was already taken.
Yes this person should be carefull. Although it probably isnt very hot,
alpha radiation is very dangerous if ingested or inhailed. Its Q values is
higher than beta or gamma also, because of its mass. When ingested, it could
go around bombarding the heck out of tissues, causing alot of problems.
