The objective of the study was to compare Bacillus subtilis sporefilm dosimeters with a Robertson Berger UV meter (RB meter)and diary records for assessing personal UV-B doses during a 13-day heliotherapy (HT) for atopic dermatitis (AD). In addition,the relationship between the personal UV-B dose and change inserum 25-hydroxyvitamin D (25(OH)D) was studied. Altogether21 ...

In recent years, interest in personal noise exposure has expanded beyond a workplace safety measure to become an effective means of investigating physiological effects of the acoustic environment on an individual. This work investigates the effects of the wearer's voice as a possible dominant sound source on body-mounted noise dosimeters and develops methods to improve the application of dosime...

Personal dosimeters based on PIN detectors have been widely used because of their simplicity and real time operation. In this paper, the optimal filter thickness and material designed by the Monte Carlo method is 1.0 mm Al plus 0.2 mm Cu. From the results of radiation characteristic analyses, the developed dosimeter has good performance when it is compared with the other conventional those as d...

We have developed a small, light, and multi-functional electronic personal dosimeter (EPD) using four semiconductor radiation detectors for dose monitoring of workers at nuclear power plants and high-energy accelerator facilities. This dosimeter is about 103 x 55 x 15 mm in size and approximately 110 g in weight, and capable of measuring gamma-ray and neutron doses in Hp(10), and beta-ray dose ...

BACKGROUND Exposure to solar ultraviolet radiation is a well-known cause of skin cancer. This is problematic for outdoor workers. In Denmark alone, occupational skin cancer poses a significant health and safety risk for around 400,000 outdoor workers. Objective measures of solar ultraviolet radiation exposure are needed to help resolve this problem. This can be done using personal ultraviolet r...

A personal UV dosimeter that can quantitatively assess high exposure solar UVA exposures has been developed. The chemical polyphenylene oxide has been previously reported on its ability to measure high UVB exposures. This current research has found that polyphenylene oxide, cast in thin film form, is responsive to both the UVA and UVB parts of the solar spectrum. Further to this, the UVB wavele...
