Bottom Line: The CCS has been used in the examination of two different types of UVP cabins routinely working in Poland.It allows precise calculation of UV doses and spatial variability of UV radiance inside the cabin, thus providing uncertainties of the doses assigned by medical staff.The CCS could potentially serve as a primary standard for monitoring various UVP cabins working in Poland.

ABSTRACT

Introduction: Ultraviolet phototherapy (UVP) is widely used in dermatological practice for the treatment of various skin diseases. Numerous studies support its beneficial curing effectiveness; however, overexposure to ultraviolet radiation can cause adverse health effects, such as sunburn reaction, erythema response, cataract, skin aging, etc. For these reasons, it is of special importance to monitor performance of UVP cabins using a calibration system to evaluate the UV doses incident upon the patient.

Material and methods: A mechanized cabin control system (CCS) is proposed. It consists of radiometers with a wide and narrow field of view to estimate the body irradiation and to identify malfunctioning cabin tubes. Quality control and quality assurance procedures are developed to keep high accuracy of the calibration procedure. The CCS has been used in the examination of two different types of UVP cabins routinely working in Poland.

Results: It allows precise calculation of UV doses and spatial variability of UV radiance inside the cabin, thus providing uncertainties of the doses assigned by medical staff. The CCS could potentially serve as a primary standard for monitoring various UVP cabins working in Poland.

Conclusions: The methodology developed to quantify UV doses in UVP cabins may be easily extended to any UV radiation source.

Mentions: The measurements of the UV irradiation in the center of the cabin were carried out by the CCS mounted on a vertical bar (Figure 3) that could rotate due to the motorized system. The CCS measured the UV changes inside the cabin during 360° rotation at 3 selected vertical levels corresponding to the height of a human face, chest, and stomach. The measurements of the UV intensity by the CCS consisted of the following stages:
