Tuesday’s New York Times had a piece entitled Radiation is Everywhere, But How to Rate Harm? It is one of the best, brief summaries of radiation risk that I have read.
The level of fear in response to Fukushima has surprised me. The nature of this fear strikes me as very difficult to mitigate.
If I was a wanna-be terrorist the level of concern demonstrated recently would certainly motivate renewed attention to use of a Radiological Dispersal Device. Evidently even a very small risk will be significantly amplified in the media and public imagination. That is the kind of return-on-investment on which the terrorist typically depends.
In any case, if you missed the original piece in the Tuesday Times, please check out online.
