original article   introduction: direct sunlight and increased heat load influence mental and physical health of workers negatively and result in performance impairment. activity reduction is a natural body response to increase in internal body temperature, and a compensatory mechanism to make body balanced. this study was carried out to estimate productivity loss due to heat exposure among ira...

OBJECTIVES The objective of this study has been to evaluate the occupational heat exposure of 12 workers at 5 plants in a subtropical country. MATERIAL AND METHODS The heat stresses and strain on workers in 5 plants were assessed by the International Organization for Standardization (ISO) 7243 index (wet bulb globe temperature - WBGT) and the ISO 7933 index (maximum allowable exposure time - ...

introduction: occupational exposure to ionizing radiation due to medical activities (both diagnostic and therapeutic procedures) has increased sharply in recent years. among the occupationally exposed workers in these fields, those most affected by this increased exposure to ionizing radiation are nuclear medicine workers. in this study, annual average effective dose, annual collective effectiv...

an extensive study was undertaken to investigate on the overall film badge service performance with which occupational radiation, exposures are reported in iran, the study involved the analysis of film badges exposed to x-and gamma rays and beta particles. for test exposures, x-rays between 60 and 140 kvpco-60 gamma radiation and sr-90 beta particles were used. the actual delivered dose equival...

background: great concern about occupational exposure to chromium (cr [vi]) has been reported due to escalated risk of lung cancer in exposed workers. consequences of occupational exposure to cr (vi) have been reported as oxidative stress and lung tissue damage. objective: to investigate the feasibility of biological effect monitoring of chrome electroplaters through analysis of serum malondial...

background: metabolic syndrome (msx) is associated with several health problems. workers are an important part of any organization. objective: to determine the prevalence of msx and related variables among office workers. methods: this cross-sectional study evaluated 1488 office workers in qom province, central iran, by using a multi-stage cluster sampling. diagnosis of msx was based on blood h...

background: noise is defined as unwanted or meaningless sound that apart from auditory adverse health effects may distract attention from cues that are important for task performance. human performance is influenced by many job-related factors and workplace conditions including noise level. objective: to study the effect of noise on human performance. methods: the participants included 40 healt...
