Radiation research in children teeth in Japan


Prof. Chihiro Ichihara from Aichi Medical University, is an independent man.

He informed the audience about the children teeth project for measuring Strontium 90, with no government support, looking for funding.

Prof. Chihiro Ichihara collects children teeth and lets them measure for Strontium 90. He plans to build an own independent lab for parents.

Similar project was done until the1980s in the U.S. after the bomb tests. It was then supervised by Jay Gould. (STRONTIUM-90 IN BABY TEETH AS A FACTOR IN EARLY CHILDHOOD CANCER

To measure Sr90 is very difficult, because it emits only beta radiation. It causes bone marrow depression, destroys the stem cells and immune system, casuses bone cancer / sarcoma.

His project deserves more attention, because it is VITAL.

Kudos to Prof. Ichihara, wo worked at the research reactor in Kyoto: “He is a physicist specialising in Neutron transport experiments and their calculation as well as in gamma-ray spectrum measurement.

Currently, he teaches as a Visiting Professor at Aichi Medical University. He is a member of the Steering Committee of PDTN. Previously, Prof. Chihiro Ichihara was an Associate Professor at the Research Reactor Institute of Kyoto University.”

Do not worry if you do not have all the information requested

There is some information we need in all cases:

  • Where the mother lived when carrying the child.
  • The child’s birthdate.
  • Where the child lived the first year after birth.

If you can supply us with this information, don’t worry about the rest if you do not know the answers.

Important: If you have a tooth or teeth from more than one child, please fill out a separate form for each child and clearly mark which teeth came from which child. We cannot use teeth from more than one child when they are mixed together.

Would you like preprinted envelopes?

For envelopes with the teeth form pre-printed on them, email us ( with your name, address, and phone, and how many envelopes you need.

* For more than 10 envelopes and Group Networking, contact our Executive Director Joseph Mangano.(
