radon is natural gas emitting the alpha ray of radiation made an occurring anion by uranium ore.
In Japan, I am known for what is spent for treatment of illness speaking of a radon hot spring, but, in the World Health Organization (WHO) or the United States of America Environmental Protection Agency (EPA), radon is recognized as cancer-causing agent which is a cause of the lung cancer next to the cigarette, and if within it, legislation meter) does every 100Bq/m3( becquerel, and, in World Health Organization (WHO) and International Atomic Energy Agency (IAEA) and International Commission on Radiological Protection (ICRP), it does the reference level of the exposure dose with indoor radon when every 300Bq/m3( becquerels indicating approximately 10mSv (millimeters sievert) per one year should not exceed legislation meter) in the area where it is difficult either.
Uranium forming radon exists in every place on the earth. It is not ventilated indoors by air-conditioning perfection, and, in the airtight high room particularly a basement, the density of radon becomes higher.
A supplier providing a technique I measure the density of radon which each state authorized in U.S.A., and to reduce an inhalational rate can ask such a supplier for a diagnostic study of the radon density to be.
However, an opinion is divided among the Japanese experts about the influence on health of the indoor radon density at present, and a specialized supplier of such a radon does not exist in Japan.
Therefore, there is measuring by oneself to examine indoor radon density in Japan for the moment.
MR -106 displays the density of radon digitally and warns it by alarm if every 100Bq/m3( becquerel becomes higher than legislation meter). There is the memory function (four hours average, 24 hours average, day average) to record a measurement result in the main body.
It is most suitable for the measurement of the radon density in indoor or the public accommodation.
