Assume that 91% of the radiation is absorbed, each alpha particle has an energy of 7.9x 10 3J, and that the RBE of the alpha particles is 15. Note that RBE is sometimes called the quality factor, abbreviated as Q. Number Sv A Previous 3 Give Up & View solution Check Answer Next Exit 8 HintExplanation / Answer
Solution:
The computation are expressed below,
mass = 61 kg = 61000
Effective dose = 61000*1.3*109*7.9*10-13*( 1 rad / 1 J*100erg/g)*107erg = 6.25*106 rad = 625 Sv
