This is an after-thought about George Monbiot claiming that Professor Geraldine Thomas said (see here) that products including calcium supplements are useless. The point of taking Calcium after a nuclear accident is that it stops the body taking up Strontium-90. Of course, there are people who think that low doses of radiation are beneficial so maybe George and Gerry Thomas are suggesting it's a bad idea even to try reducing your exposure to internal Sr-90. If so they are in a very small minority.
If on the other hand they are saying Calcium doesn't block Strontium, a simple Google search will return lots of advice for people who are taking stable Strontium as a remedy for osteoporosis. It includes the advice that, because the two elements are chemically similar, they will compete at absorption sites if taken at the same time. Even dairy foods should not be eaten within a few hours of taking Strontium.
