These detectors are ideal for the measurement of low-dose environmental gamma radiation which constitutes one source of external exposure. Measurements were conducted by a qualified Radiation Protection Supervisor (Class 1 Working Environment Measurement Specialist). <\/p>\n<p>External exposure to radiation in the environment derives not only from artificial sources, but also from natural sources (cosmic radiation, naturally occurring radio-nuclides). Natural background radiation dosage varies with a variety of factors, although the average value for exposure in the Tokyo Metropolitan Area is considered to be approximately 0.04\u03bcSv\/h. (average values at various sites throughout Japan measured with <a href=\"http:\/\/www.rada.or.jp\/database\/home4\/normal\/ht-docs\/member\/detail\/040253.html\" target=\"_blank\">the Institute of Radiation Measurement\u2019s Hakarukun detector<\/a>, and values calculated by <a href=\"http:\/\/www3.starcat.ne.jp\/~reslnote\/A8_8.htm#30\"><\/a>the Geological Society of Japan<\/a>.) <\/p>\n<p>The environmental radiation levels measured at the various campuses are between 0.04 and 0.11\u03bcSv\/h. If natural background radiation dosage (approximately 0.04\u03bcSv\/h) is subtracted from these figures, levels are between 0 and 0.07\u03bcSv\/h. Such levels are well within the effective dose limit recommended by the International Commission on Radiological Protection (ICRP) for general public exposure. <\/p>\n<p>Click on the placemarks <img loading=\"lazy\" decoding=\"async\" src=\"\/jp\/news11\/data\/redpoint.png\" width=\"13\" height=\"16\"><img loading=\"lazy\" decoding=\"async\" src=\"\/jp\/news11\/data\/bluepoint.png\" width=\"13\" height=\"16\"> on the dose rate measurement map to display the measurement site numbers. <\/p>\n<p>The &#8216;Location&#8217; points noted with the \u2020 symbol on the dose rate measurement results table, and <img loading=\"lazy\" decoding=\"async\" src=\"\/jp\/news11\/data\/redpoint.png\" width=\"13\" height=\"16\"> on the map, will be measured periodically in the future.
