EDUCATIONAL SET GEIGER-MÜLLER GM is the simplest version dedicated for schools, higher education and other institutions or people who wish to familiarize themselves with radioactivity phenomena or perform educational activities in this field. The device is based on SBM-20 Geiger- Müller counter to measure X and gamma radiation.
The main elements are mounted at plywood board with acrylic surface. At this board it is marked the following things: the distance (cm) and angles. It allows for demonstration of many education experiments which are describing for example radiation attenuation with distance.
The set consists of manual with information related to the device itself, exemplary experiments. It also presents basic knowledge of radioactivity with many graphics and drawings.
EXPERIMENTS
- comparison of radioactive items and accessible samples which contain radioactive materials: spark plugs, Vaseline glass, thoriated welding TIG rods, kitchen salt, hand clocks, record album dusters, neon bulbs, uranium glass, granite and many others
- demonstration of natural background (some additional “check” source should be also used to verify operation of instrument and different dose rates)
- demonstration of radiation range in paper, kitchen foil, cardboard, aluminium, acrylic glass and other materials
- how Geiger-Müller (G-M) is working - familiarization with G-M counter operation principle, calculation of counter dead time and range of working voltage
- ionizing radiation units and quantities (Sievert, Grey), other physical and operational quantities which describe the radioactivity phenomena and ionizing radiation field
DETECTED RADIATION:
- X > 30 keV
- ɤ 30 keV ÷ 1,25 MeV
CONSTRUCTION
The device is based on SBM-20 Geiger-Müller counter to measure X and gamma radiation in the wide energy spectrum. The results are displayed at backlit monitor (cps, µSv/h), and radiation intensity is signalled proportionally by counter clicks and diode blinking.
TEACHER’S GUIDE (RADIOACTIVITY)
It contains the description of few experiments linked with radioactivity phenomena, which can be realized by the teacher using this educational set. Moreover, the guide has a lot of interesting facts and information about ionizing radiation introduced in a very easy way. It helps to transfer the knowledge from teacher to student thanks to many graphics and drawings, which are showing proposed ways of teaching about the radioactivity.
