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.

Figure 0008: The solar UV irradiance by the Brewer spectrophotometer and output of the YES UVA-1 meter from simultaneous measurements at Belsk, Poland, on August 12/13, 2010. The straight line shows the least-squares regression line

Mentions: Figure S1 shows the regression line based on the data collected at Belsk on 12–13 August 2010. Here we found b = 24.14 ±0.61 (2σ) W · m−2 · V−1. The instrumental constant calculated from other experiments was close to this estimate, i.e., 24.07 (July 2, 2010) and 23.65 (2–3 August 2010). After simple mathematical manipulations with (S.1), (S.2), and (S.3) it can be obtained that α = β < fSOLAR>. If we select b = 24.14 and <fSOLAR> = 0.589 finally we arrive at α = 14.22.
