  • Radiation accident or radiation incident? When are IRR17 contingency plans appropriate?

    A few blog posts back we discussed radiation accidents in industrial radiography. We provided examples where immediate action was required to prevent or reduce exposures to ionising radiation. Where a radiation accident is reasonably foreseeable, IRR17 requires contingency plans to be available and rehearsed. There seems to be an expectation by many employers (and regulators) that local rules will always have contingency plans (or a reference to them). The potential for a radiation accident is determined by your radiation risk assessment. Are radiation users providing contingency plans regardless of the risk, and the definition of a radiation accident? Let's discuss.

    Drop and run (from a radioactive Co-60 source) has featured in a number of blogs and articles over the years, and more recently in some online videos from content creators. From a shock perspective many of these paint a pretty grim picture (and this is not without merit). However, third or 4th hand information tends to muddy the waters and inaccuracy creeps in. This article provides some radiation safety data and comment on the principles of drop and run, and in particular some analysis of the infamous Co-60 source picture which has found itself onto t-shirts and cushions!

  • RPA bodies recognised by HSE (IRR17). Is Ionactive an RPA body? No! Do we need to be? No!

    The UK Health and Safety Executive (HSE) has a system to recognise RPA Bodies (Radiation Protection Adviser Bodies). Those recognised will appear on a 'List of RPA bodies recognised by HSE under IRR17'. Ionactive Consulting Limited is not a RPA body and is not on this list. Does this matter? What does being on the list mean? If you are looking for a RPA should you only choose from this list? This brief article explores RPA Bodies in the UK.
