Po-210 preparation (alpha radiation)

Emits alpha radiation (polonium 210) with a nominal activity (A) of 0.1 µCi (3.7 kBq)
and an energy level of 5.304 MeV (100%).The half-life period is 138 days.

According to the General Austrian Radiation Protection Ordinance (AllgStrSchV) this
radiation source is below the exemption limit of 10 kBq. Therefore the preparation is
not considered as a highly-radioactive radiation source in respect of the AllgStrSchV.
The source is supplied in a disc which is pressed into a cylindrical acrylic glass
sheating; afterwards this is closed with glue. A sticker with radiation warning symbol
indicates the source.
Dimensions of the acrylic glass cylinder: D= 30 mm, H = 12 mm
