Hypothesis
The study aims to measure the luminance level of X-ray viewing boxes and ambient lighting levels in reporting rooms as a quality assurance procedure.
Conclusion
The radiograph viewing conditions in Johannesburg variably comply with guidelines.
Supporting Evidence
- The mean average luminance was 1026.75 cd m-2 at the Division of Radiology and 3284.38 cd m-2 at the Division of Radiation Oncology.
- The average ambient lighting was found to be 66.30 lux and 66.43 lux at the Division of Radiation Oncology and Division of Radiology respectively.
- The Division of Radiation Oncology had an average viewing box uniformity of 7.14% compared to 27.32% at the Division of Radiology.
Takeaway
This study looked at how well the lighting conditions for viewing X-rays at a hospital meet recommended standards, and found that they don't always match up.
Methodology
Luminance levels of X-ray viewing boxes and ambient lighting were measured using a calibrated photometer in reporting rooms.
Limitations
The study did not analyze compliance with European guidelines due to differences in measurement distance.
