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 ...
