Background and objective: Oral isotretinoin is the only treatment that has an effect on all the major etiological factors involved in acne (Increased sebum production, alterations in microbial flora, hyperkeratinization of pilosebaceous duct, and inflammation). Considering complications and relative expense, several treatment regimens have been suggested. The objective of this study was to eval...

Introduction: Total body irradiation (TBI) is a form of external beam radiotherapy which is used in conjunction with chemotherapy with the purpose of immunosuppression. Since the target in TBI is the whole body so a uniform dose distribution throughout the entire body during TBI is necessary. As recommended by AAPM dose variation must be within ±10% of prescription dose. A revi...

Background: Total Body Irradiation (TBI) is different from standard radiotherapy in many aspects, so it is not easy to predict the delivered dose to the patient under TBI treatment. Diode dosimetry procedures for surface dose reading can help to define variations of the actually delivered dose from the prescribed one. The aim of this study was to describe the measurements made to calib...

The potential radiation dose for the Solar-B EIS CCDs was discussed in reference [1], and the potential effect of that radiation dose was discussed in reference [2]. Whilst the effect of ionising radiation on CCD areas such as flat band voltage shifts was not a cause for concern (although the transient effects on image quality may be) there was a potential problem with the effect of Non-Ionisin...

This Chapter deals with two tests we performed on our wafers in order to evaluate the total dose response of RHbip1 technology. The practical aim was to establish the reliability of the voltage regulator in an LHC-like radiation environment. Moreover irradiation data for test structures were also taken and analyzed, in order to get more into the damage physics. We made tests with neutrons and p...
