2018.06.28 Dear friends and supporters
Status Report (June, 2018)

We are pleased to present attached to this letter our very first status report on the "Preserving Deciduous Teeth Network" Project.

We have since 2015 expended great effort in establishing the Network, enlisting the support of a large number of individuals and organizations from across Japan and the world, driving forward our plan of creating our own Strontium-90 detection and measurement capability and, last but not least, secure sufficient initial funding to get the project off the ground.

By end July 2018 we will finally be ready to commence the ''real “ work, i.e. to start the programme of measuring the Strontium-90 contamination in the teeth already in our hands.

The project ‘s financial situation remains precarious; the financial summary attached to the status report shows that our financial resources are exhausted; we will have to undertake strenuous efforts to secure additional income for the next project phase.

Despite these difficulties we will pursue our objectives with single-minded determination; we are hopeful that our supporters will continue to assist us in this endeavour.

We would be deeply grateful for your continued support.

Dear friends,

Today I need to share some sad news with you.

We have lost one of our precious friends and supporters of the ''Preserving Deciduous Teeth Network“, Dr Shuntaro Hida, who passed away on March 20. He had just celeberated his 100th birthday on January 1.

As you know, he was a survivor of the Hiroshima A-bomb attack. On the morning of August 6, 1945 he was in Hesaka Village, about six kilometers from ground zero, where he was treating a sick child. From there he witnessed the explosion of the bomb and saw the mushroom cloud growing above Hiroshima City. Unable to return to his hospital in Hiroshima City despite his determined efforts, he set up an emergency care unit in Hesaka Village, where he subsequently treated more than 6,000 of the injured. His care for Hibakusha did not end there; he continued to help and care for them tirelessly throughout his life.

Dr Hida was the first one to make me aware of the health hazard of internal radiation exposure, and he was to highlight this risk again and again in the wake of the Fukushima catastrophe.

Kazuko, my wife, and I had the honour of saying our last good-byes to Dr Hida on 24 March. He looked very peaceful in his eternal sleep, wearing his favourite deep- red jumper.

I still remember what he told us when he was visiting Gifu Hospital some years ago: ''Physicians must do things wholeheartedly. If not, don't even try to become a physician.“ Indeed, that was Dr Hida: he did everything wholeheartedly. He devoted his entire life to providing medical care to his patients and helping sufferers - wholeheartedly.

Sincerely

Eisuke Matsui

Sechs Jahre Fukushima: Die Atomkatastrophe besteht fort

What is the 'Preserving Deciduous Teeth Network'?


The Preserving Deciduous Teeth Network (PDTN) is an initiative that aims at creating a nationwide network of people contributing their children's shed deciduous teeth. The collected teeth will be examined to determine the concentration of Strontium-90 deposited within them.


What for do we preserve deciduous teeth?


1) As a result of the Fukushima Daiichi Power Plant accident large amounts of artificial radioactive materials were released into the environment, one of which is Sr-90. To date no surveys have been conducted to determine Sr-90 levels that have been absorbed into the human body. However, this can be achieved by measuring concentrations of Sr-90 in deciduous teeth.

2) This project is to protect the lives and the health of the children. Based on the results of our surveys we will determine the occurrence/levels of radiation exposure and analyse the health effects induced by it. The findings will be used to make our recommendations to the citizens, the Japanese Government and municipalities.

3) In order to properly investigate the health effects on the children, our surveys need to be comprehensive and cover the whole country.

Please help us by donating the shed teeth.
Thank you!
