Endress + Hauser Australia introduces the Gammapilot M FMG60 for radiometric measurement. These radiometric measurement devices offer a way to significantly reduce radioactive source activity and lower the risk category and level of security reporting required to comply with the ARPANSA Code of Practice RPS11 for the Security of Radioactive Sources (2007). ARPANSA stands for the Australian Radiation Protection and Nuclear Safety Agency, a Federal Government agency charged with the responsibility of protecting the health and safety of people and the environment from the harmful effects of radiation. Its RPS11 code regulates security for the storage, possession, use and transport of radiological materials, including radioisotopes, to minimise the risk of these materials being accessed by persons with malicious intent.
Radiometric measurement, commonly used for determining density, continuous level and level limit, requires operators to ensure compliance with RPS11. If the radiation source used has a high enough activity to be considered high risk, then additional security measures must be implemented. These measures often involve significant operational expense plus the risk of fines for non-compliance. Reducing the radioactive source activity and lowering the risk category can translate into huge cost savings.
When the Gammapilot M FMG60 PVT scintillation detectors are used for density, their high sensitivity means that the required source activity can be significantly reduced. Even with low radiation levels there is a high pulse rate available for signal evaluation. Typically the required source activities can be reduced by a factor of between two and three.
