Optimal mapping of terrestrial gamma dose rates using geological parent material and aerogeophysical survey data.
Regulatory authorities need ways to estimate natural terrestrial gamma radiation dose rates (nGy h⁻¹) across the landscape accurately, to assess its potential deleterious health effects. The primary method for estimating outdoor dose rate is to use an in situ detector supported 1 m above the ground, but such measurements are costly and cannot capture the landscape-scale variation in dose rates ...
متن کاملGamma-ray localization of terrestrial gamma-ray flashes.
Terrestrial gamma-ray flashes (TGFs) are very short bursts of high-energy photons and electrons originating in Earth's atmosphere. We present here a localization study of TGFs carried out at gamma-ray energies above 20 MeV based on an innovative event selection method. We use the AGILE satellite Silicon Tracker data that for the first time have been correlated with TGFs detected by the AGILE Mi...
متن کاملA survey of pathogenic genes from diarrhea stool samples obtained in Nara prefecture.
We conducted a survey of diarrhea stool samples in which no virulent agents had previously been detected at clinical laboratories. DNA extracted directly and purified from the diarrhea stool was tested for bacterial pathogenic genes by polymerase chain reaction. The test results for 85 specimens were as follows: one sample was positive for lt, ipaH, and eae; two were positive for aggR; and eigh...
متن کاملMeasuring γ–ray dose of terrestrial samples using β-γ Spectrometry
Background: The existence of some radionuclides in soil and some building materials produce a β-γ radiation field, which in some regions the exposure of these radionuclides to human is high. Materials and Methods: The air-absorbed dose, indoor and outdoor annual effective dose of soil and some building material samples (ceramic, granite, gypsum, etc.). The samples were collected from 3...
