background: application of dose-area product (dap) quantity has been increased in the clinical practice. dap is relatively easy to measure. dap has been shown to correlate well with the total energy imparted to the patient, which is related to the effective dose. material and methods: in this study, measurements of dap were carried out in a sample of 421 adult patients who underwent conventiona...

background: natural background radiation of a particular region is one of the distinctive factors defining the status of environment. eloor island is an industrial area in ernakulum district of the state of kerala, india. the indoor and outdoor gamma level measurements have been carried out for the region for evaluating the annual effective dose to the population residing in this area. material...

Background: For radiotherapy of total skin including sub-cutaneous tissue up to a depth of 3 cm on the entire left leg of an adult (Angiosarcoma skin), a complex treatment with multiple stationary electron fields was planned at our clinic. The details of dosimetry, clinical dose measurements are presented. Materials and Methods: The treatment planned with 6 overlapping 9 MeV electron fields in ...

Introduction: In this study, organ radiation doses were calculated for the renal agent 99mTc-DTPA in children. Bio-kinetic energy of 99mTc-DTPA was evaluated by scintigraphy and estimates for absorbed radiation dose were provided using standard medical internal radiation dosimetry (MIRD) techniques.Material and Methods: In this applied research, fourteen children patients (6 males and 8 females...

The non-cancer mortality data for cerebrovascular disease (CVD) and cardiovascular diseases from Report 13 on the atomic bomb survivors published by the Radiation Effects Research Foundation were analysed to investigate the dose-response for the influence of radiation on these detrimental health effects. Various parametric and categorical models (such as linear-no-threshold (LNT) and a number o...

CONTEXT Several varicella vaccines are available worldwide. Countries with a varicella vaccination program use 1- or 2-dose schedules. OBJECTIVE We examined postlicensure estimates of varicella vaccine effectiveness (VE) among healthy children. DATA SOURCES Systematic review and descriptive and meta-analysis of Medline, Embase, Cochrane libraries, and CINAHL databases for reports published ...
