Assessment of risk at workplace: A study on radiographers work practices in Vizag Steel

The main purpose of this study is to assess the health risks posed by radiographers and to determine whether existing controls at work place are adequate. This small survey conducted in the year 2002. All nine (male) radiographers aged 35-45 years (median 38 years) and control subjects (24) who were matched for sex, age (within 3-5 years) interviewed using a questionnaire about symptoms experienced during and off work. There were no smokers. The total number of symptoms experienced by the radiographers was greater than controls. Symptoms like headache, and skin irritation were persistent in two radiographers during and off work. Visual observations revealed that, all the radiographers while on work used lead aprons and film badges. Results of personal exposure to ionizing radiation were within the normal limits. Identified hazards in the working environment are (i) exposure to ionizing radiation, (ii) exposure to chemical contaminants. Based on the subjective judgment of radiographers, existing work practices and personal exposure results to ionizing radiation, the estimated risk level was moderate. Risk control action plan developed to bring the risk level to tolerable.
