Fixed Radiation Gauges

Fixed radiation gauges are used in civil construction, oil, petroleum and mining industries as an essential part of the monitoring arrangements within the process plant to measure the density or mass flow of a material flowing through pipework. It consists of a small radioactive source (typically a Caesium 137 isotope) that emits a beam of gamma radiation through the material flowing through the pipework, to a detector placed on the opposing side. The radiation source (usually measured in GBq or TBq of activity) is sufficient to effect human health and therefore the gauges are constructed of steel to provide shielding and radiological protection of the workforce.

Fixed radiation gauges are registered with the Radiological Council and legislated under the Radioactive Substances Act. Under the Act, a Radiation Safety Officer (RSO) is appointed who is required to ensure that the gauge conforms to the relevant Codes of Practice during transports and operations, to ensure that the external gamma dose rates are below the legal limits and are ALARA. RadPro are licenced RSOs to several end-user clients and are experts in the control, monitoring, management and transportation of fixed radiation gauges, as well as addressing incidents under emergency arrangements.
