Germanium detector shield

Our low background lead castle models:

Nuclear Shields designs and manufactures germanium detector shields, also known as low background lead castles. These detector shields have an inner shielding of lead with a lower amount of Bq/Kg. This lead is also called low background lead or virgin lead. This lead is mostly found on the bottom of the sea in old shipwrecks from the 1800s.

Germanium detectors in gamma spectroscopy

Gamma spectroscopy is used to determine the identity of gamma emitters in a gamma source. It is a required tool in radiometric assay. By measuring a gamma emitting source with a germanium detector it is possible to determine which gamma emitters are present and in which quantity.

The low background lead has a lower amount of Bq/Kg. This means that it is very suitable for use in high precision measurements. Low background lead is integrated in our detector shields to provide an inner environment with as little background radiation as possible. This low background radiation environment will improve the lower limit of detection and reduce counting times.
