  • Radon gas in schools (and other workplaces)

    Published: Jul 23, 2023

    • Radon
    • Schools
    • HSE
    • Radiation exposure
    • Risk assessment
    • Radon assessment
    • Exposure estimate
    • Dose Limits
    • IRR17
    • Bq/m3 Radon to dose
    • Bq/m3 Radon to Sv

    Recently a private school was prosecuted and fined by HSE for exposure to radon gas : "Boarding school fined £50,000 after pupils overexposed to radon radioactive gas". There is a lot of information online regarding radon exposure, so this article does not intend to describe radon from start to finish. Instead we take a look at what we know from the HSE statement and information found in the press, and undertake some exposure / radon concentration estimations. Furthermore, we highlight some particular issues that schools and other workplaces should consider - one is that even where you have a radon potential of < 1% (lowest category), depending on your specific circumstances you could still have a radon exposure problem and you may need to carry out a risk assessment and radon monitoring.

  • New UK IRR17 consent - dose rate and accelerators

    Published: Jul 14, 2023

    • IRR17 Consent
    • HSE
    • Ionising Radiation
    • Accelerators
    • Linac
    • Radiotherapy
    • Dose Rate
    • 7.5 micro Sv/h

    [Main article updated October 2023]. At the time of writing (mid July 2023), ONR have released their guidance on the new IRR17 consent process. We are now awaiting HSE to do the same before October 2023, but our understanding is that ONR / HSE guidance will be practically identical. So Ionactive has been looking at the ONR guidance, and following some interesting comments on various radiotherapy related forums, we are drawn towards the accelerator guidance (safety assessment form). In particular the phrase 'estimates must show that dose rates do not exceed 7.5 micro Sv h-1 outside any shielded enclosure'. The correct interpretation of this phrase is critical.

  • Ionactive radiation protection resources - an update for 2023

    Published: Feb 26, 2023

    • Radiation Protection resource
    • Radiation protection glossary
    • radiation protection links
    • Radiation safety rules of thumb
    • technical radiation protection

    The Ionactive website (and Ionactive as a company) have always been a little different. Yes, there is a commercial side where we offer Radiation Protection Adviser (RPA) services and radiation safety training (such as our online Radiation Protection Supervisor course). However, since we started (2002), Ionactive has offered an extensive free radiation protection resource hub which is much more than a few selected links. This new blog entry for 2023 highlights new resource and updates to existing resources.

The definition of 'safe' is not strictly an engineering term; it's a societal term. Does it mean absolutely no loss of life? Does it mean absolutely no contamination with radiation? What exactly does 'safe' mean?
