Abstract
Background
The use of radiation in the health sector is of tremendous diagnostic and therapeutic benefit to patients. However, scatter radiation associated with its use poses detrimental risks to occupational staff and other health personnel whose activities are associated with the use of radiation. Therefore, there is a need to ensure effective monitoring of occupational exposed health personnel. Presently, the effectiveness of this programme at the biggest tertiary hospital in Ghana is however unclear.
Aim
The aim of this study was to investigate if occupationally exposed radiographers in the biggest tertiary referral hospital in Ghana were monitored in compliance with international regulations.
Methods
A quantitative descriptive survey design was used to obtain data on radiation monitoring in the biggest tertiary referral hospital in Ghana from February 2014 to April 2014. Two different tools, observation and questionnaire, were employed for data collection from 50 radiographers purposively sampled in the study. The data was analysed with Microsoft Excel 2010.
Results
A 100 % response rate was obtained. All respondents were monitored by means of a TLD badge except 4(8 %) who did not have any personal radiation monitoring device. Although 86 % of respondents confirmed that their personnel dosimeters were collected for reading after 3 months of use, all the respondents however, did not receive TLD readings feedback until after 3 or more months. In particular, 38 % of diagnostic radiographers claimed they never received any feedback, while 66 % respondents indicated radiation monitoring in their various departments were unsatisfactory. Delays from the service provider (regulatory body) were identified as the causes of irregularities in supply of dosimeters and monitoring feedback.
Conclusion
Radiation monitoring of occupational personnel at the biggest tertiary hospital was unsatisfactory and did not meet required standards. Hospital management and the regulatory body should ensure strict compliance with international regulations for purposes of achieving occupational radiation safety.
