A passive dosimeter designed to measure exposure to hydrogen fluoride was tested under laboratory conditions over the concentration range of 0.56 – 4.47 mg HF/m. The lowest concentration was chosen to be close to the Polish TLV (0.5 mg HF/m). The dosimeter consists of a Whatman No.1 filter paper impregnated with K2HPO4 placed in a polyethylene holder protected by a polyethylene screen. After ex...

The Air Force sponsored flight tests using damage dosimeters, fabricated by The Boeing Company, to measure temperature and structural dynamic strains on B-52, F-15 and C-130 aircraft. The dosimeter measurements help diagnose difficultto-analyze structural conditions, such as acoustics and high cycle fatigue, and support the durability patch design process to repair secondary structure cracks. T...

In this article we describe commissioning and implementation procedures for the Dose Verification System (DVS) with permanently implanted in vivo wireless, telemetric radiation dosimeters for absolute dose measurements. The dosimeter uses a semiconductor device called a metal-oxide semiconductor field-effect transistor (MOSFET) to measure radiation dose. A MOSFET is a transistor that is general...

Measurement of the lateral profile of the dose distribution across a narrow x-ray microbeam requires a dosimeter with a micron resolution. We investigated the use of a MOSFET dosimeter in an "edge-on" orientation with the gate insulating oxide layer parallel to the direction of the beam. We compared results using this technique to Gafchromic film measurements of a 200 micrometer wide planar x-r...

Polycrystalline ammonium dithionate has been examined for its radiation response in the low dose range (<5Gy) using EPR technique. The SO(3)(-) radical ion was detected as a single EPR line with a peak-to-peak derivative width of ca. 0.44mT in irradiated samples and its intensity was found to vary linearly with dose. At equal and moderate settings of microwave power and modulation amplitude amm...

This paper provides an overview of the characteristics of a phenothiazine-mylar dosimeter which can be used as an effective solar UVA exposure assessment tool. This dosimeter is sensitive to UVA wavelengths (315-400 nm); its performance has been characterized in a series of tests such as (a) UVA exposure response (dose-response), (b) temperature stability of the response, (c) impact of long ter...

The semi-solid flow battery (SSFB) is a promising storage energy technology featured by employing semi-solid fluid electrodes containing conductive additive and active Li-ion battery materials. The state of art anode material for SSFB is Li4 Ti5 O12 (LTO). This work shows that LTO improves drastically the performance in fluid electrode via hydrogen annealing manifesting the importance of the el...
