The British nuclear tests occurred in the 1950s, as I understand it, primarily in remote areas of Australia and a range of different islands. The British Nuclear Tests Act only provides cancer treatment for those who were exposed during the tests in certain places; they are eligible to get white cards that provide payment for any cancer treatments they may have. I don't know the details. I'll have to get back to you on the levels of compensation. But certainly people had some level of coverage through some of the schemes that were in place at that time.
