Occupational Exposure & Ionising Radiation Monitoring

Airborne Contaminants

The Health and Safety Executive provides detailed guidance and UK statutory limits on the exposure of workers to airborne pollutants. This includes many highly toxic compounds like carbon monoxide and cyanide as well as less obvious pollutants, like dust, which can cause adverse health impacts.

At Phlorum we can provide the monitoring equipment and analysis of results that allow employers to comply with the law and protect their staff from occupational exposure to potentially damaging air pollutants. This often involves equipping staff with personal air sampling equipment at their workplace and monitoring them over an eight hour working day period.

Radiation Monitoring

Ionising Radiation

Ionising radiation can come from a variety of sources in industrial and commercial settings. However, stringent measures are usually in place to prevent emissions of ionising radiation or radioactive materials from affecting workers – e.g. use of radionucleotides in laboratories, use of nucleonic gauges in industry, use of X-rays in medical facilities.

In the oil and gas sector, there is particular risk to workers from exposure to ionising radiation from the accumulation of radioactive plaques and scales that build up over time from gases and minerals reacting with pressure changes in pipework and tanks as oil and gas is pumped from deep below the earth’s surface. As these plaques and scales accumulate, which are referred to as TENORM (Technically Enhanced Naturally Occurring Radioactive Material), the amount of radiation they emit increases, which can pass through the pipes and tanks that contain them or spread in contaminated materials when containment is broken. Making staff aware of ionising radiation risks, which cannot be detected without specialist monitoring equipment, is therefore very important; as is identifying the sources of radiation before they potentially become harmful.

Phlorum staff hold licenses for handling research grade radionucleotides and other radioactive materials, and have Radiation Protection Supervisor qualifications for measuring and managing ionising radiation exposure at industrial facilities. Our staff have carried out ionising radiation exposure awareness training for staff on offshore oil and gas facilities and have completed TENORM monitoring surveys on operational offshore platforms and onshore processes.
