  • Build a Pocket Ionizing Radiation Detector (PIRD)

    Get yourself a chunk of granite, it is mildly radioactive and shows a noticeable increase on a Geiger counter compared to background radiation. I'm a school science technician and this is what I issue for students to handle, as the sealed radioactive sources can only be used for teacher demonstrations.Unfortunately I'm about 4 years late with this comment... but felt the need to add this for reference!!
