Effective dose from natural background radiation in Keffi and Akwanga towns, central Nigeria
Background: Human is exposed to radiation in their environment with or without their consent and the exposure to natural background radiation is an unpreventable event on earth. Materials and Methods: An in situ assessment of the indoor and outdoor background radiation in Akwanga and Keffi towns of Nasarawa state Nigeria was carried out using a halogen-quenched Geiger Muller (GM) detector (Insp...

متن کاملNatural radiation background in metropolitan Taipei.
A high-pressure ionization chamber was used to measure the natural background radiation in metropolitan Taipei, Taiwan, R.O.C. during a period in 1987-1988. The average exposure rate was 27.55 x 10(-10) C kg-1 h-1 including cosmic radiation, but the radon contribution was excluded. Scintillation survey meter, gamma-ray spectroscopy for soil samples, in-situ measurement with a NaI(Tl) detector c...
متن کاملDose measurement, its distribution and individual external dose assessments of inhabitants in the high background radiation areas in China.
As a part of the China-Japan cooperative research on natural radiation epidemiology, we have carried out a dose-assessment study to evaluate the external exposure to natural radiation in the high background radiation areas (HBRA) of Yangjiang in Guangdong province and in the control areas (CA) of Enping prefecture since 1991. Because of the difficulties in measuring the individual doses of all ...
متن کاملNatural Gamma Radiation and Effective Annual Dose in Hot Springs in South Khorasan Province, Iran
Background and purpose: Background radiation exists naturally in the environment and human has been always exposed to it. These rays can affect living creatures and cause chromosomal damage, and genetic and somatic diseases. Hot water springs are a major source of background radiation. This study aimed at investigating the absorbed dose of environmental gamma and determining the annual effecti...
