Martin This project seeks to make the subject of ionizing radiation accessible and understandable to students at levels from middle school to medical school through semi-quantitative laboratory experiences. The vehicle for doing this is a suspension of micro-droplets of a liquid, which are super heated at room temperature, in a gel. The energy carried by the ionizing radiation triggers bubble formation. The cavitation which initiates the bubble produces a "pop" which can be amplified enabling easy counting of the event. In Phase II experimental kits for each include vials of the suspension, electronic circuits and appropriate instructional materials.
