Report of a nationwide survey on actual administered radioactivities of radiopharmaceuticals for diagnostic reference levels in Japan
OBJECTIVE The optimization of medical exposure is one of the major issues regarding radiation protection in the world, and The International Committee of Radiological Protection and the International Atomic Energy Agency recommend establishing diagnostic reference levels (DRLs) as tools for dose optimization. Therefore, the development of DRLs based on the latest survey has been required for nu...
متن کاملThe xenon record of extinct radioactivities in the Earth.
Analyses of xenon from well gas rich in carbon dioxide reveal a large excess of radiogenic xenon-129 from the decay of extinct iodine-129. Smaller excesses observed in the heavy xenon isotopes are from fission. These results place narrow limits on any age difference between the earth and the oldest meteorites. The occurrence of excess radiogenic xenon-129 in well gas also suggests that any quan...
متن کاملPetrology and Geochemistry of Boninite Series Volcanic Rocks, Chichi-jima, Bonin Islands, Japan
An Eocene submarine boninite series volcanic center is exposed on the island of Chichi-jima, Bonin Islands, Japan. Five rock types, boninite, bronzite andesite, dacite, quartz dacite, and rhyolite, were distinguished within the boninite volcanic sequence on the basis of petrographic and geochemical observations. Boninite lavas contain high magnesium, nickel, and chromium contents indicative of ...
متن کاملThe Suicide Pandemic of Hydrogen Sulfide Poisoning in Japan
Background: Hydrogen sulfide (H2S) suicides have been frequent in Japan in recent years. This study was performed to describe the epidemiologic profile of an outbreak of H2S suicides in Japan. Methods: In September 2008, questionnaires about patients involved in H2S suicides were sent to 250 hospitals in Japan. Data collected from each patient included gender, age, clinical manifestations, date...
متن کاملCurrent state of bone scintigraphy protocols and practice in Japan
Objective(s): Nuclear medicine technologists in Japan often perform additional single-photon emission computed tomography (SPECT) with or without computed tomography (CT) after whole-body imaging for bone scintigraphy. In this study, we wanted to identify the bone scanning protocols used in Japan, together with the current clinical practices. Methods:...
