Outline of Final Research Achievements

Radiation sources and measurement devices usable safely as educational tools were developed. The radiation sources were fabricated from potassium chemical fertilizers and kelps. Those raw materials contain potassium-40 emitting natural radiations. The radiation measurement devices consisted of a GM counter and several circuit units including high voltage power supply and counter circuit. Those were all handmade, and parts used as materials were empty coffee cans,injection needles, capacitors, diodes, microcomputer, and others, being generally well known and obtained with ease. Besides, a series of slides (Power point) for explaining units of radiation (Bq, Sv, cpm, etc.) and data sheets showing a training procedure were also made as being improved based on actual radiation educational courses. To spread our own developed educational techniques, manuscripts were published and presentations were made at various academic meetings, international conferences, and research meetings.
