Numic Expansion in the Southern Sierra Nevada

Recent research indicates that late prehistoric Numic expansion onto the western slope of the southern Sierra Nevada was facilitated by a competitive edge held by migrating groups, mainly Great Basin­derived settlement and subsistence behaviors fine­tuned to the uncertainties of living in Little Ice Age mountain environments. But ethnographic, linguistic, and archaeological evidence also sugges...

Gamma background radiation in Yazd province A preliminary report

 ABSTRACTBackground: There are relatively rich uranium mines in regions of Saghand and Bafgh in Yazd province. This survey was carried out to provide a map of ambient gamma radiation of Yazd province and the probable effects of the existence of these mines on background radiation dose rates.Materials and Methods: The measurements of the outdoor and indoor–environmental exposures (including cosm...

Terrestrial background radiation studies in South Konkan, Maharashtra, India

Background: The natural radionuclides are always present in soil and care needs to be taken to minimize the radiation dose to humans. These radionuclides are mostly gamma ray emitting radionuclides which contribute to the radiation dose in long term behavior of radionuclides in soil. Health hazards associated with natural radioactivity are of great concern and it is necessary to assess risk due...

Annual background radiation in Chaharmahal and Bakhtiari province

Background: Measurement of background radiation is very important from different points of view especially for human health. The aim of this survey was focused on determining the current background radiation in one of the highest altitude regions ( Zagros Mountains ), Chaharmahal and Bakhtiari province, in the south west of Iran . Materials and Methods: The outdoors-environmental monitoring exp...
