Co-60 preparation (gamma radiation)

Emits gamma and beta radiation (cobalt-60) with a nominal activity (A) of 1 µCi (37 kBq),
the half-life period is 5.3 years. In addition to beta radiation,
which is absorbed by the radiation window,
it emits gamma rays with an energy level of 1.17 and 1.33 MeV.

According to the General Austrian Radiation Protection Ordinance (AllgStrSchV)
this radiation source is below the exemption limit of 100 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. This source is supplied with two lead-cylinders for protection of radiation.
Dimensions of the acrylic glass cylinder: D= 30 mm, H = 12 mm
