Bench For Radioactivity Experiments. A bench for radioactive sources and GM-tubes, providing stable and convenient setup, allowing reproducible results when making experiments with radioactivity. Investigate how the radioactive radiation spreads from the source in both angle and distance or investigate how radiation is absorbed by lead and aluminium.The bench is 60 cm in length, with millimetre scale. Two riders are included, one for carrying GM-tube, and the other for carrying the source holder*.The source holder can be fitted with 6 mm diameter steel rod, for hanging absorber plates in front of the radioactive source. It can be rotated, and is fitted with degree scale ±110° ×1°• Lead plates: 5× mm thick, and 10× mm thick (enamelled to protect from lead contamination)• Aluminium plates: 6× mm thick, and 4× 0.5 mm thick*Please note: This holder is only suitable for use with Frederiksen radioactive sources, which are available by special request only. The sealed radioactive sources can be used instead, with some limitations, using RA170800 source holder.
