1 Calculate the binding energies per nucleon for the isotopes 5B10, 6C12, 7N14 and 8O16. Do the results support our guess that odd-odd isotopes are in a lower class of stability than even-even isotopes?

Data: Atomic masses in amu.

2. You are supplied with a sample containing 7.5 µg of the isotope I131. Given the decay constant of this isotope is 9.96 ´ 10-7 s-1, find

  i)  the half life of the sample.

ii)  the activity of the sample.

  iii)  the activity of the sample in threeweeks time.

  iv)  if, in legal terms, the sample is radioactive (I131 is legally defined as a radioactive substance if it has an activity greater than 40 kBq.) If it is, how long will it remain so?
