Question
The power obtained in a reactor using U235 disintegration is 1000 kW. The mass decay of U235 per hour is
Options
A.10 microgram
B.20 microgram
C.40 microgram
D.1 microgram
Solution
According to Einstein’s mass energy relation
E = mc2 or m =
Mass decay per second
Mass decay per hour
× 60 × 60 = 
(3600 s)
= 4 × 10-8 kg = 40 × 10-6 g = 40 μg
E = mc2 or m =
Mass decay per second
Mass decay per hour
× 60 × 60 = (3600 s)= 4 × 10-8 kg = 40 × 10-6 g = 40 μg
