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.

Full and open circles mark narrow band UVB TL-01 tubes and broad band UVA TL-09 tubes, respectively. The arrows show the anticlockwise rotation of the calibration unit. The rotation angles are shown round in the circle

Mentions: Two types of medical cabins were examined: MEDISUN 2800 PC-AB in Lodz, and MEDISUN-2800-44-PC-AB in Poznan. The whole body phototherapy was performed in those cabins using narrow band UVB (TL-01) and broadband UVA (TL-09 UV-A) fluorescent tubes (Philips Lighting B.V., Roosendall, the Netherlands). The irradiance spectra of the tubes, measured inside the cabin by a USB2000+ spectrophotometer (Ocean Optics Inc., Dunedin, Florida, USA), are shown in Figure 1. There are 12 TL-01 and 16 TL-09, and 16 TL-01 and 32 TL-09 tubes mounted in a round assembly in LPC and PPC, respectively, as presented in Figure 2.
