Hiroshima bomb / Radium Dial painters
There is a lot of data from the victims of the A bombs detonated over Hiroshima and Nagasaki at the end of World War 2.
This has yielded a large amount of information concerning increased cancer risk and other effects which has been responsible for the dose limits changing in the UK in 1999.
Other sources of data are also listed:
- Chernobyl,
- Radium Dial painters,
- bone cancer by ingestion from licking end of brush that was dipped into radium paint,
- early radiologists,
- weapons test observers,
- Chernobyl incident and
- in vitro cell survival studies to name but a few.
