Radon is a naturally occurring colourless, odourless, radioactive gas formed by the decay of the small amounts of uranium that occur naturally in all rocks and soils. It is present in all parts of the UK, although concentrations vary depending on the local geology.

The radioactive elements formed by the decay of radon can be inhaled and enter our lungs. Inside the lungs, these elements continue to decay and emit radiation, most importantly alpha particles.

These are absorbed by the nearby lung tissues and cause localised damage. This damage can lead to lung cancer.

What will we do to help?

Bradley Environmental has expanded its range of workplace and environmental safety services with the introduction of radon risk management to help employers meet their safety responsibilities.

Under the new service, Bradley Environmental will provide an initial risk assessment to identify those areas where radon measurement devices should be installed and develop a schedule to establish the priorities and programming for testing.

In situ monitoring will be carried out in designated locations over a three month period to allow for variations in levels of any gas detected. After this period the test results will be assessed and any necessary remediation works determined, depending on the gas levels found.

What are your legal duties?

To protect employees against this risk, the Ionising Radiation Regulations 1999 apply to workplaces where radon is present. Employers are legally required to assess the risks to the health and safety of their employees and in the case of radon gas are required to take appropriate action to restrict exposure when its presence is above defined levels.

The average radon gas level in UK homes is 20 Bq m-3. For levels below 100 Bq m-3, the individual risk remains relatively low and is not a cause for concern. However, the risk grows as the radon level increases and at levels above 400 Bq m-3 employers are required to take remedial action.

Increased exposure to radon increases the risk of lung cancer and, as the single largest source of radiation exposure to the UK population, it is responsible for an estimated 1,100 lung cancer deaths each year.

How can I test for radon?

Testing for radon gas is easy and inexpensive. Bradley Environmental provide a variety of short-term and long term tests for both commercial and domestic use. Our detectors are small, discreet and are fully validated by Public Health England. Our radon monitors have been specifically designed to meet the highest professional standards and have a proven track record. Bradley Environmental can provide a placement and collection service for your convenience.

OK, I'm interested what do I do next?
