History

"Low Dose Radiation Research Center" was established in October, 2000, aiming to promote the low dose radiation research further, and to send the results of the research widely, staring at the 21st century when radiation and human race's relations become important more and more in the point like the use of the radiation in the medical treatment and industry and peaceful uses etc. of nuclear power. LDRC originally proceeds the research of the biological effects of low dose radiation, strengthens the cooperation with an external organization, as a base on the research network, tries to collect and to send the information of the biological effects of low dose radiation connected with the correct understanding and its application.
