dosimetry for radiodiagnostics (2). It has been used for personal dosimetry (as a replacement for film badges) and medical dosimetry for both radiotherapy and radiodiagnostics (2,3). The dosimeters (nanoDot, Landauer, Glenwood, Illinois) used in our study are OSL based, small (1 1 0.2 cm), environmentally stable, and highly accurate and precise within the exposures measured in the study (3). Ad...

Ultraviolet-B (UV-B) radiation and elevated tropospheric ozone may cause reductions in the productivity and quality of important agricultural crops. However, research regarding their interactive effect is still scarce, especially on the belowground processes. Using the open top chambers experimental setup, we monitored the response of soil nematodes to the elevated O3 and UV-B radiation individ...

Savannah River Site (SRS) operating contractors have continuously maintained excellence in the control of radiation exposures to both Site workers and the public in the surrounding area. In doing so, Site organizations and radiation protection officials have contributed significant advances to the nuclear industry in methods for controlling radiation exposures. These methods, developed and firs...

The radiation environment encountered by astronauts during spaceflight is far more complex than any radiation field existed on Earth. Space crew living and working in the International Space Station (ISS) are exposed to a mixed radiation field comprises primary high-energy cosmic rays, including energetic protons and heavy ions, and to secondary radiations, including energetic neutrons, produce...

divides into the Lorisiform lemurs and the Lemuriform lemurs. There is some justification for this, yet the unique features of the Malagasy (Lemuriform) lemurs does argue that the nocturnal lorises of Asia and Africa are better kept in a separate category. But here we go arguing terminology, a deplorably bad habit which Sir Wilfred has noted is a characteristic trait of students of the Primates...

BACKGROUND In recent years, much attention has been paid to occupational stress, but relatively little or no research has been conducted on the influence of knowledge, attitude, and practice of radiation protection (RP-KAP) on job stress among radiation workers. OBJECTIVES This study aims to assess job stress among health care workers in Iran who are occupationally exposed to radiation in ord...

introduction the exposure of human beings to ionizing radiation from natural sources is a continuing and inescapable feature of life on earth. for most individuals, this exposure exceeds that from all man-made sources combined. materials and methods in this study, the annual effective dose in high level environmental background radiation areas (hlebras) of northern city of ramsar in iran was de...

In the context of a medical surveillance program aimed at preventing cancer risk from exposure to ionizing radiation, we investigated chromosomal damage in peripheral lymphocytes from 37 hospital workers exposed to low levels of ionizing radiation and 37 controls. The micronuleus (MN) assay was used as a biomarker of genetic damage. The influence of confounding factors like smoking status, age ...
