  1. Thank you so much for your work, we really appreciate you sharing your results.

    1. Thank you so much for your comment. We are trying our best to get the most meaningful results, but mushroom is very hard to get enough volume with good density. Actually the lab saw a small peak at 622Kev for Cs137. We need a sample with better condition to detect it.
