UNESCO Chemistry Teaching Project in Asia: Experiments on Nuclear Science.

This teacher's guide on nuclear science is divided into two parts. The first part is a discussion of some of the concepts in nuclear chemistry including radioactivity, types of disintegration, radioactive decay and growth, and tracer techniques. The relevant experiments involving the use of radioisotopes are presented in the second part. The experiments include the use of Geiger counters, investigations of the properties of radiations, and separation techniques such as paper chromatography, ion exchange, solvent extraction and precipitation. A simple circuit diagram of a Geiger counter is included. This handbook is intended primarily for teachers of secondary school science in Asia. (LC)
