nuclear physics exercise
The activity from a mixed radioactive sample is measured at different times and given in a table like this:
Time (h)...Decays/sec
-----------------------
0.0 ...... 7500
0.5 ...... 4190
1.5 ...... 3100
: ...... :
: ...... :
12.0 ..... 280
I am now supposed - based on this table - to determine how many different nuclids the sample consists of along with their half-lives. How can I possibly extract that information uniquely from that table (the numbers in the table aren't exactly the right ones, since I can't remember them).
maybe the table needs some explanation, because of the crappy layout; the left-hand column is the time in hours and the right-hand column gives the corresponding activities (I haven't written the complete table).
