Ionactive Radiation Protection Blog
Our radiation protection blog is predominately written by Mark Ramsay, Radiation Protection Adviser (RPA) for Ionactive Consulting. It contains a mixture of content including day to day descriptions of RPA work, advice and comment on current radiation protection issues, comment on regulator (HSE etc) inspections (suitably sanitised), historic content (i.e. the Co-60 drop and run story, Alexander Litvinenko Po-210, Fukushima nuclear accident, industrial radiography accidents), radiation safety legislation updates and practical radiation protection in the workplace.
For formal radiation safety advice. please see our Radiation Protection Adviser (RPA) service pages.

Read moreFollowing the release of our 'Alexander Litvinenko - "Polonium-210 Poisoning" - revisiting an Ionactive 2006 blog article' on the 27 November 2022, this latest blog post compares what Ionactive assessed (including activity calculations) at the time in 2006, with official estimates of Po-210 intake and dose assessment (as submitted to 'The Litvinenko Inquiry' report issued January 2016).

2022 Alexander Litvinenko - "Polonium-210 Poisoning" - revisiting an Ionactive 2006 blog article
Published: Dec 27, 2022
Read moreOn the 24 November 2006 Ionactive released a blog article "Polonium-210 Poisoning", partly as a response to a BBC article "Radiation found after spy's death" published on the same day. This article is over 16 years old and we have not changed it (other than to tidy up formatting to remain compatible with our modern website). So there are assumptions, and probably some errors. But it is Ionactive history so we keep things as they are - we have come a long way since then. A key question we asked at the time, and long before there was anything much in the media or scientific community, was this - How much Po-210 was used?

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?
