that thing she is holding is a xrf (x-ray florescence) it uses radiation to give percentages of metals present in rocks and soils. it should never be pointed at a person and when used (at least in the states) as a primary tool for work you have to wear a tld badge to measure the does of radiation for yourself for year. in short this if the pic for the future. i think i will buy a small lake up north after i sell in 2015.
