Radiation Hazard Awareness Among Healthcare Workers in Nyeri County, Kenya

The widespread use of radioactive equipment in hospitals necessitates adequate knowledge and tools among healthcare workers to prevent and monitor radiation exposure. The study investigated the effectiveness of radiation protection in the detection of exposures among healthcare workers in Nyeri County, Kenya, focusing on radiation exposure levels, level of awareness, and control measures. Using a cross-sectional design, the study targeted 1121 healthcare workers, with a sample of 294. Data was collected through semi-structured questionnaires and a checklist, generating both quantitative and qualitative data. Dosimeter read-outs were conducted for one month and a radiation safety assessment survey in the Radiology department was also conducted using a radiation detector meter. Quantitative data were analyzed using SPSS version 27, employing descriptive and inferential statistics, while qualitative data were analyzed thematically. Findings revealed that about half of the healthcare workers had not received training on radiation hazards, and less than half were aware of the maximum permissible dose limit for adults. Approximately half of the workers knew that the eyes, thyroid glands, ovaries, and testis are susceptible to radiation hazards. The study recommended comprehensive and regular training programs for all healthcare workers, emphasizing the correct handling of lead aprons and the consistent use of personal protective devices such as lead aprons, lead glasses, portable lead shields, automatic interlock devices, and thyroid shields.
