Objective: Different categories are available for estimating of radiation dose. Radioisotopes with the same energy and almost the same physical properties have similar effects. Monte Carlo technique is a computerized method based on mathematical simulation of physical processes. The main purpose of this study is to show that beta particles are not able to penetrate deep into the water. also dif...

Several national and international organizations have developed various types and levels of external audits for radiotherapy dosimetry, either based on on-site review visits or using mailed dosimetry systems. Three major TLD (thermoluminescent dosimetry) networks make available postal dose audits to a large number of radiotherapy centres on a regular basis. These are the IAEA/WHO TLD postal dos...

background: radioiodine therapy has proven to be an effective method in the treatment of patients with differentiated thyroid carcinoma after thyroidectomy. the scope of this study is to describe a method to obtain the dose of organs using medical internal radiation dosimetry (mird) method. at the end, the results of mird calculations were compared with thermoluminescent dosimeter (tld-100). ma...

Abstract Introduction: This is the second of two papers giving an overview use Monte-Carlo techniques for radiotherapy applications. Methods: The first paper gave introduction and introduced some codes that are available to user wishing model different aspects treatment. It also aims serve as a useful companion curated collection on have been published in this journal. Results Conclusions: focu...

Medical dosimetry education occupies a specialized branch of allied health higher education. Noted international shortages of health care workers, reduced university funding, limitations on faculty staffing, trends in learner attrition, and increased enrollment of nontraditional students force medical dosimetry educational leadership to reevaluate current admission practices. Program officials ...
