indoor natural radiation level in hamadan province, 2012
abstract background and purpose: people are always exposed to ionizing radiation, which could badly influence their health. the degree of these influences depends on the level of radiations. in this study the dose of indoor gamma radiation was assessed using rds-110 multi-purpose survey meter. materials and methods: to determine the dose rate of indoor radiations in cities of hamedan province f...
متن کاملRadiation effects in the Marshall Islands
On March 1, 1954, the detonation of a thermonuclear device on Bikini in the Marshall Islands resulted in the accidental deposition of fallout on several inhabited atolls and on a Japanese fishing vessel. The accident was unusual in that the explosion, occurring near ground level, resulted in a heavy, particulate fallout on Rongelap and Ailingnae, about 160km away. Utirik, further to the east, e...
متن کاملNatural velocity of magnetic islands.
The phase velocity of magnetic islands is calculated in the semicollisional regime with cold ions. Two solution branches arise, corresponding to islands propagating with the ions and with the electrons. For the ion branch the phase velocity and the polarization current are small. For the electron branch, the phase velocity depends on the ratio of W, the half-width of the island, and rho(s), the...

متن کاملThe Impact of Low-level Exposure to Radiation in Natural Ecosystems of Najaf and Dhi Qar Cities, Iraq
Introduction: This study investigated the exposure rates of background radiations in selected locations of Najaf and Dhi Qar cities, Iraq. Materials and Methods: Exposure rates were quantified using a portable Geiger–Müller meter. Frequent readings of gamma dose rates were recorded (82 and 101 nGy h-1). Results: The lowest absorbed doserate was found to be 43.5±17.4 nGyh-1 in Najaf (outdoor e...
