Radon - updated guidance

Some of our keen readers may have noticed that the HSE have produced an updated Code of Practice (CoP) after the 1999 Ionising Radiation Regulations (IRR99) were superseded on 1st January 2018, by the Ionising Radiations Regulations 2017 (IRR2017).  More info here 

As Radon falls under these Regulations, HSE are also looking to update guidance on Radon in the workplace.  We have had a quick peruse of the CoP which confirms general obligations and duty of care are unchanged.

The new Regulations reduce the eye dose limit and some work will now require HSE notification.  This appears to be when working in an atmosphere containing radon 222 gas at an annual average concentration exceeding 300Bq/m-3.

If the exposure assessment level is reduced from the current 400 to 300Bq/m3, it could mean that the Action Level for houses will also reduce (this is currently set at 200Bq/m3).  The exposure assessment level and action level are linked, this could result in more houses falling into areas requiring radon protection.

We will keep an eye on this and update clients when necessary.
