The study included 93 employees at 17 preschools in the county of Umeå located in northern part of Sweden. Personal daily noise dosimeter recordings were made at five representative work days. Stationary noise recordings were made during the same days at two departments of each preschool, in the playing halls and in the dining rooms. Besides audiometric tests, the employees rated their experien...

The objective of this study was to develop new scales measuring knowledge and attitude about UVR and sun related behavior, and to examine their association to sun related behavior objectively measured by personal dosimetry. During May-August 2013, 664 Danes wore a personal electronic UV-dosimeter for one week that measured their UVR exposure. Afterwards, they answered a questionnaire on sun-rel...

Fricke solution has a wide range of applications as radiation detector and dosimetry. It is particularly appreciated in terms of relevant comparative advantages, like tissue-equivalence when prepared in aqueous media like gel matrix, continuous mapping capability, independence of dose rate and incident direction, as well as linear dose response. This work presents the development and characteri...

Following a previous feasibility study, a photon dosimeter have been constructed by attaching a small piece of BGO scintillator to a low attenuation plastic optical fiber for which the light output is measured with a current-type PMT. The dosimeter model is tested in a Co irradiation chamber in the dose rate range varying from about 50 to 1200 Gy/h. The dose rates are measured at a number of pr...

PURPOSE To determine whole body and hand radiation exposure to the hand surgeon wearing a lead apron during routine intraoperative use of the mini C-arm fluoroscope. METHODS Four surgeons (3 hand attending surgeons and 1 hand fellow) monitored their radiation exposure for a total of 200 consecutive cases (50 cases per surgeon) requiring mini C-arm fluoroscopy. Each surgeon measured radiation ...

This work investigated the suitability of passive dosimeters for reference dosimetry in small fields with acceptable accuracy. Absorbed dose to water rate was determined in nine small radiation fields with diameters between 4 and 35 mm in a Leksell Gamma Knife (LGK) and a modified linear accelerator (linac) for stereotactic radiosurgery treatments. Measurements were made using Gafchromic film (...
