Product Details

General, Organic and Biological Chemistry Nuclear radiation is potentially harmful to living organisms. Despite its potential danger, nuclear radiation has been harnessed for many beneficial purposes, including nuclear medicine and nuclear energy. How do workers in hospitals and nuclear power plants protect themselves from the harmful effects of nuclear radiation? In this experiment, students compare the properties of alpha, beta and gamma radiation. The activity (counts per minute) of low-level α, β, and γ sources are measured using a Geiger-Müller radiation detector, which “counts” the number of atoms ionized by nuclear radiation. Students investigate the relative penetrating power of α, β, and γ radiation by measuring how the recorded activity changes when they place different materials between the source and the detector. The effectiveness of different shielding materials will also be determined. Complete for 24 students working in groups of three. Radioactive sources and measuring equipment are required and available separately.
