I was delighted that we achieved a satisfactory demonstration of our reactor emergency arrangements. The scenario was realistic, but testing. The quality of the exercise documentation produced by Ionactive was as usual first class.

Came knowing very little about the subject, have left with all of the relevant knowledge I need

Mark, it's been great working with you over the last year, not only is our house in better order but the wider workforce genuinely appreciate the time you have spent reassuring them

Radon Gas - a surprise! I work only with security x-ray systems but found the radioactive bits of the course interesting too. I will be talking to my colleagues about Radon Gas when next discussing our workplace risks!

Many thanks for an interesting two-day radiation course. Whilst physics and maths is not my thing, I found the material easy to digest and surprisingly enjoyable!
