background: ˝radioadaptive response˝ is well-documented phenomenon appeared in low dose ionizing radiation received in vitro and in vivo. occupational exposure has always been a great concern for radiation workers therefore this study was performed to study radioadaptive response in terms of residual dna double strand breaks as an endpoint in peripheral blood leukocytes of occupationally expose...
background: in some areas of ramsar, a city in northern iran, residents receive a much higher annual radiation exposure than is permitted for radiation workers. induction of adaptive response in residents of ramsar has been reported previously. in this study induction of such a response in short term exposure to high background levels of gamma radiation is investigated. materials and methods: f...
background: the aim of the study was to analyze the effective dose record of occupationally exposed radiation workers at bahawalpur institute of nuclear medicine and oncology department. materials and methods: annual effective doses of occupationally exposed workers were measured by film badge dosimetry by sending the dosimeters to radiation dosimetry laboratory (rdl), pakistan institute of nuc...
this study investigates the effectiveness of the kriging interpolation model and the emission weighted proximity model (ewpm) in assessing relative exposure risk of air pollution using results from the american meteorological society/epa regulatory model (aermod) as benchmarks. we used simulated exposure risk to so2 in the dallas area in texas in this evaluation. results suggest that the relati...
cement dust exposure is associated with increased respiratory impairment. as the major occupational hazard in the cement production industry is cement particles, our aim was to more thoroughly examine the acute effects of occupational exposure to cement dust on the respiratory system. a cross-shift study was conducted in a cement factory in iran. 100 high exposed workers from production and pac...
background: brucellosis is the most common bacterial zoonosis worldwide. greece has the highest reported incidence among eu countries. however, occupational risk factors have not been well described. objective: to determine the incidence patterns and exposure risk factors of brucellosis in greece. methods: we used national-level surveillance and occupational denominator data to estimate the inc...
background: indian tea industry workers are exposed to various exposures at their workplace. objective: to investigate the respiratory health of indian tea industry workers. methods: we administered a respiratory questionnaire to and measured lung function in workers of 34 tea gardens and 46 tea factories. we used correlation matrices to test the association between their respiratory symptoms a...
tire manufacturing industry has a history of more than half a century in iran, where 14 thousand workers are employed. the old and semi-automated processes equipment, backward technology, and raw materials impurity lead to significant exposures to occupational carcinogens such as benzene. this study was to assessment of benzene exposures and evaluation the resulting cancer risk in two tire-manu...
researchers suggested that the individual fit test be conducted to estimate the protection effectiveness of workers’ hearing protection device (hpd) while working. practically, it is convenient to conduct single, instead of multiple, fit test measurement. this study examined if a single trial of earplug fit test can represent multiple performances. additionally, it investigated how much noise e...
background: exposure to human blood and body fluids is a common risk for nurses. many factors can affect the prevalence and incidence of this occupational hazard. psychosocial factors at work may be a risk factor for the exposure. objective: to assess needle stick, sharp injury and mucus exposure to blood-borne pathogens among nurses in iran and to determine the association between these exposu...
