A radiochromic silicone based dosimeter has been fabricated that allows for threedimensional (3D) dose verification. This paper characterizes the silicone dosimeter and verifies previous results found by other research groups. Using a recipe found to be dose rate independent, we identify the spectra of the dosimeter irradiated to different doses and verify that the response from different dose ...

The Damage Dosimeter has been designed to fill a void in commercially available data recorders. The United States Air Force often has the need to measure structural strains and temperatures on in-service aircraft in order to diagnose difficult-to-analyze structural conditions, such as high cycle fatigue. To perform these functions a rugged, small, and lightweight data acquisition unit called th...

PURPOSE To evaluate the effects of overlapping dose volumes for varying field arrangements in two formulations of PRESAGE®: one intended for, and irradiated with, proton beams and the other photon beams. METHODS For each treatment modality (photon, proton), three overlapping field setups were performed. These included a stationary dosimeter irradiated over six fractions, a dosimeter shifted l...

A two-screen sampler (an effective dosimeter), with a collection efficiency matched to the particle size response of the radon progeny dose conversion factors (DCF), obtained from the ICRP respiratory tract model as implemented in the computer code RADEP, has been developed to assess the inhalation dose from exposure to radon progeny. In order to evaluate the performance of this sampler, the se...

Abstract In vivo dosimetry for patient radioprotection is a real challenge concerning new radiotherapy treatments. this study we aim to develop dosimeter based on tissue equivalent material, flexible and adaptable the morphology in order perform complex irradiation beams. Here, report evaluation standard beams of highly composed silicone elastomer containing leucomalachite green as radiochromic...

Background: The purpose of this study is to fabricate inexpensive in-house low cost homogeneous and heterogeneous human equivalent thorax phantom and assess the dose accuracy of the Treatment Planning Systems (TPS) calculated values for different lung treatment dosimetery. It is compared with Thermoluminescent Dosimeter (TLD) measurement. Materials and Methods: Homogeneous and heterogeneous tho...

A practical exercise for developing a simple cost-effective solar ultraviolet radiation dosimeter is presented for use by middle school science students. Specifically, this exercise investigates a series of experiments utilising the historical blue print reaction, combining ammonium iron citrate and potassium hexacyanoferrate to develop an ultraviolet sensitive solution. The activity is intende...

In order to measure a three-dimensional dose distribution in X-ray radiotherapy, we developed TL slab dosimeter with new TL phosphor Li3B7O12(Cu), which has Zeff = 7.42 and a density of 1.01 g/cm 3 and synthetic resin as binder [1].We can measure a three-dimensional dose distribution easily and reliably using this detector. This detector showed a promising tool for QA/QC in advanced X-ray radio...
