- The study reviewed foods testing for cesium 137 contamination and also strontium 90 contamination.
- Official assumptions had been than there was a set ratio of cesium 137 to strontium 90 across all foods.
- This is even more problematic as testing for actual strontium 90 in foods is done less often due to the complexity of the testing method.
- What was found is that over time the ratio of strontium 90 in foods had increased.
- A new study in the journal Environmental Science & Technology looked at governmental food testing in Japan.
