Question.

I have a commercial property in Cornwall, which has a radon level of 415Bq/m3.

Technically, this makes me a radiation employer, and required to appoint a RPA and comply with the IRR.

Practically though, I will do some basic building remedial works that will ensure the radon levels fall below the action level, and re-measure annually.

For the c 3 months it will take to get the building works completed, does anyone think it's worth me appointing an RPA?

This is a response/question so I am prepared to be shot down in flames.

I have been an RPS many years ago so I'm a bit rusty, but I was under the impression that naturally occurring radiation (in this case radon from granite I presume?) does not fall into the hard and fast rules of radiation protection. If there is something quick and easy (reasonably practicable as opposed to practicable) then I would do it but to go down the route of appointing RPA's and RPS's is a bit extreme. The local tea shops will probably need the same and most homes in parts of Cornwall would fall into this category.

A view from the HSE (notoriously reluctant to make a non-general statement) would really be of use here!

I confess I haven't read this, but does this not answer your question?
