Day 9 7/20/2015

 


                    Today we went to the Wellpinit school for a safety presentation. I met Randy Barnes, Robert Nelson, Gerald Cates, Michelle Veron, Lue Miller, and Bobby. They all talked about being safe while in the mining area. I also learned that there are seven different radiations. The first radiation is cosmic radiation this type of radiation comes from outer space. The second radiation is terrestrial radiation this comes from rocks,soil, ore, etc. The third radiation is internal radiation this one comes from inside the body. The fourth radiation is indoor radon this comes from the soil under your house its a product of uranium.
