I know that Australia's universities have top-level researches in these topics. However, I do not know if in Europe or U.S. or Canada is this a current trend.
If anyone could tell me which universities there are to study this I would appreciate it. I am a geologist from Brazil and I am interest in these fields (mainly applied to ore exploration) to study for my master's degree. I also have interest in gamma-ray spectrometry for prospecting ore deposits.
