Here's a ques. I am having problem with:
sample of gold is bombard with 2*10^10 neutrons per sec. it cause the Au(A=197) become radioactive (Au(A=198)) which decay with half life time of 2.969day (through beta decay
1. how many Au(A=198) will be after 5 days of bombardment?
2. how many Hg(A=198) will there be after 5 days?
3. what is the number of radioactive Au(A=198) at equilibrium and what will be the activity of the sample?
im having problem getting the differential equations right here, ill be very happy for any help. thank you so much in advance
