Advanced Physics for Brachytherapy 2018

Dosimeter characteristics/requirements :

(1) Sensitivity : must be high enough for low dose rate measurements. If the sensitivity is too high, it may cause rapid saturation at high dose rate (2) Adequate dose range and (preferably) linearity of the response as a function of accumulated dose (3) Insensitivity of response to influence quantities (dose rate, temperature, pressure, directional effect, accumulated dose, etc.): response should be independent, or variation should be known or measurable in order to perform adequate correction (4) Energy response : preferably independence of response as a function of energy (5) Repeatability : stability for repeated measurements over a short period of time & Reproducibility : stability of material, construction, etc. over a long period of time (6) Accuracy/precision : the derivation of the dose from the dosimeter response must be possible with minimum uncertainty, but the requirements may differ for different applications
