Recently, a friend of mine sent me a series of samples from Japan. He, my friend, lives in Japan and obtained these samples at some personal risk. I have started the process of testing each of the many samples using gamma spectroscopy and other techniques. I will be posting my results for each sample as I test them, which may take time given my busy work schedule.
As you can see, the analysis did detect a possible 85 Krypton contaminant, as well as other curious spikes. Please take a look and see what information you can detect from this spectrum and the accompanying data.
