Calcium as a blocker for uptake of strontium

Calcium as a Strontium uptake blocker is mainstream

This is an after-thought about George Monbiot's claim that Professor Geraldine Thomas said (see here) calcium supplements are useless. The point of taking Calcium after a nuclear accident is that it stops the body taking up the radioactive element Strontium-90.
The web has lots of advice for people who are taking stable Strontium as a remedy for osteoporosis. It includes the advice that calcium and strontium shouldn't be taken at the same time because they are so chemically similar that they will compete at absorption sites. Even dairy foods should not be eaten within a few hours of taking Strontium.
