1 Bq 1 disintegrations 1 Ci 37x1010 Bq 1 rad 001 Gy 1 Gy 1

1 Bq= 1 disintegration/s

1 Ci= 3.7x10^10 Bq

1 rad= 0.01 Gy

1 Gy = 1 J/(Kg tissue)

1 rem= 0.01 sv

1 sv= 1 J/Kg

If a 50kg person is uniformly irradiated by 0.10 J alpha radiation,

Part A

What is the absorbed dosage in rad?

Part B

What is the effective dosage in rem?

Solution

(a)radiation=50*.1=5J

5J=5Gy,5Gy=.05rad so radiation emmited is .05 rad

(b)radiation=50*.1=5J

5J=5sv,5sv=.05rem so radiation emmited is .05 rem
