Radiation Assessment & Management

EMF, ionising radiation and radiation management plans for industry.

Radiation in the workplace takes many forms.

Radiation in the workplace takes many forms – from electromagnetic fields (EMF) generated by high-voltage electrical infrastructure, induction heating equipment and wireless communications systems, to ionising radiation encountered in radiography, nuclear gauging and mineral processing operations. Both categories carry real health risks when exposures are not properly understood and managed and both are subject to regulatory oversight that demands documented evidence of assessment and control.

RED OHMS Group provides radiation assessment and management services to clients in mining, resources, infrastructure and industrial sectors. Our occupational hygienists are experienced in identifying radiation hazard sources, quantifying worker exposures and developing the management frameworks that demonstrate compliance with applicable legislation – including the Radiation Safety Act 1975 (WA), state-based radiation protection regulations and the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) requirements where they apply.

Capabilities

Systematic assessment of workplace sources of electromagnetic fields and ionising radiation, including measurement and characterisation of exposures, comparison against applicable exposure limits (ARPANSA RPS3, ICNIRP guidelines) and identification of workers at elevated risk.

Development of site-specific radiation management plans that satisfy regulatory requirements, including source inventories, exposure control strategies, monitoring protocols, emergency response procedures and record-keeping systems. Ongoing monitoring programmes to verify the continuing effectiveness of controls.

Understanding Your Radiation Obligations

Ionising radiation sources – including X-ray gauges, density meters, level sensors, nuclear moisture gauges and industrial radiography equipment – are common in mining and processing operations.

Operators of these sources carry specific licensing, registration and management obligations under state radiation safety legislation. Failure to meet these obligations exposes organisations to significant regulatory liability, quite apart from the direct health risks to workers.

Electromagnetic fields from high-power electrical equipment, induction furnaces, radio-frequency welding and telecommunications infrastructure can cause acute biological effects at sufficiently high levels and are subject to the ARPANSA Reference Levels and, in workplaces, to the general duty of care provisions under WHS legislation. EMF assessments are increasingly requested by workers and their representatives, particularly at sites with new infrastructure or process changes.

RED OHMS Group brings a scientifically grounded, practically focused approach to radiation management. We help you understand what sources are present, what exposures your workers may be receiving and what measures are proportionate and effective. Our radiation management plans are written to satisfy both the technical requirements of the relevant regulator and the operational realities of your site.

FAQs

Yes. In Western Australia and most other jurisdictions, the possession and use of radioactive sources – including sealed sources in nuclear gauges – requires a licence and the licensee must maintain documented procedures for the safe use, storage, transport and emergency response associated with those sources. A radiation management plan is the standard vehicle for meeting these documentation requirements.

Ionising radiation – including X-rays, gamma rays and alpha and beta particles – carries enough energy to remove electrons from atoms, which can damage biological tissue and DNA. Non-ionising radiation, including EMF from power lines, radio frequencies and microwave sources, does not carry sufficient energy to ionise atoms but can cause thermal effects and other biological responses at high levels. Both types are assessed and managed by Red Ohms.

Yes. We can assist with responding to regulatory notices, conducting gap assessments of existing radiation management arrangements and developing or updating documentation to bring your operations into compliance. Early engagement with a qualified occupational hygienist is strongly recommended when regulatory issues are identified.
