#iteachphysics Looking at alpha radiation of a Thorium welding rod and Beta radiation of Lo-Salt using the @pascoscientific geiger counter from @SciChemEdu The student could not see this at school because it was considered too dangerous by his teacher #Physics This is as safe as it gets. Both Lo-Salt - salt high in KCl rather than NaCl is considered safe to eat and by many considered to be a healthier eating habit. The thorium rods are used in welding and easily available in welding shops. No need to worry about radiation on the health warnings - yet as soon as I get the geiger counter out many teachers panic about the danger to the children - I assume its the geiger counter that is so dangerous.
