    One last question regarding problem number 4: If I am having trouble finding mass excess data for a specific isotope, I assume it is okay to use the NNDC Q-value calculator to find the value?

      Please use any resource, including Q-value calculator, as needed.

    It looks like 244Fm for question 9.2 doesn't alpha decay ?? maybe I am mistaken.

      Nevermind, used Q-value calculator.

      The decay for 244Fm is primarily spontaneous fission with a half life of 3.2 ms. There may be an alpha decay but if the half life is long, which you can estimate from the Geiger-Nuttall equation, it will not be easily observable.

      And yes the q-value calculator is a good tool to use.

    Anyone computer savvy? I'm still having issues getting ERG software to work on my laptop.

      I will post this link on the website. It is a bit less stable than the BNL site but has excellent information.

    So apparently my comment I attempted to post when this quiz was first posted didnt go through, but I was just gonna comment about the question that asked if U238 decayed to Th231. Some students thought it didn't while others thought it did, but since you already answered my question by email I thought I'd just make it clear that it does!
