Physiotherapist's perception of risk from electromagnetic fields

Abstract

Research has documented concern among physiotherapists regarding the use of electromagnetic radiation in physiotherapy departments, in particular the use of short-wave diathermy. The purpose of this study was to examine how physiotherapists perceive their risk of exposure to radiofrequency radiation at work in the context of known environmental and lifestyle risks, and whether they felt in a position to protect themselves against any possible risk. Data were collected by postal questionnaire sent to 225 physiotherapists working in hospital-based physiotherapy departments. The response rate was 90%. There was no significant difference between the ratings of risk perception between physiotherapists who worked in a department where short-wave diathermy equipment was available and those who did not. Exposure to radiofrequency radiation in the physiotherapy department was perceived as low risk and it was also seen as the risk respondents felt best able to protect themselves from. These findings when interpreted in the context of previous research suggest that physiotherapists realize they can protect themselves from any potential risks associated with using short-wave diathermy but may be complacent regarding the dangers involved.
