Study radiation in lost baby teeth

Berkeley, California

Regarding the July 16 article “Fukushima cattle shipments banned“: If cows that ate tainted straw 75 kilometers from the site of the Fukushima No. 1 nuclear plant have internal radiation at levels of concern, then human beings who ate local produce are probably similarly affected.

While there has been a lot of reportage on external radiation sources, the internal exposure of local Japanese citizens — especially children and young women — should be examined more closely.

As a pediatrician, I can suggest that one easy way to examine this exposure is to ask parents to donate for study the teeth that their young children shed.
