Sarday, O cber 7, 2017 the expander. Radiation oncologists and medical physicists will need to consider what effect the gas filled chamber and metal components within the expander have on their treatment planning and dosimetry. Breast air expanders require a wedged pair planning technique however, Saline expanders can be planned with a IMRT hybrid technique. It is critical to understand the con...

INTRODUCTION The increasing use of radiation sources of high activity for industrial and medical applications and in the generation of electric energy and the consequent increase in the probability of to occur accidents, becomes important the research and the development of detectors and dosimetry methods for quality control of the applied doses. The radiation dosimetry is important for all rad...

background: therapeutic radiopharmaceuticals are designed to deliver high doses of radiation to selected target organs with an aim of minimizing unwanted radiation to surrounding healthy tissue. due to the potential of targeted radiotherapy to treat a wide range of malignant conditions, [153sm]-samarium maltolate was developed for possible therapeutic applications. materials and methods: the or...

The ENEA Radiation Protection Institute since many years has been playing a reference role in Italy in the radiological protection field for external exposures and for incorporated radionuclides dosimetry both in the industrial and medical activities. A series of laboratories and measurement facilities are in operation in connection with neutron, photon and electron metrology, with the developm...

Iodine-131‑labeled monoiodohypericin (131I‑Hyp) is a necrosis avid compound used as a complementary anticancer agent. Herein, the biodistribution in rats with re-perfused partial liver infarction (RPLI) was used to estimate its human internal radiation dosimetry. Iodine-123‑labeled monoiodohypericin (123I-Hyp) as a safer surrogate for 131I-Hyp was prepared with iodogen as oxidant. Determination...

In nuclear medicine and particularly in internal radiotherapy, one of the major challenges is to determine the dose for each patient. Current internal dosimetric estimations are based on the Medical Internal Radiation Dose (MIRD) formalism and use standard mathematical models. These standard models are often far from a given patient morphology and do not allow to perform patient-specific dosime...

Medical professionals involved at intraoperative fluoroscopy are exposed to low doses of the occupational radiation exposures. The biological effects of chronic low-dose radiation on human health are complex and have not been well established. The aim of the present study is to follow up hematological parameter changes during 2 years in medical professionals exposed to ionization radiation in o...

Information about the consequences of human exposure to radiation in the former Soviet Union has recently become available. These data add new insights and provide possible answers to several important questions regarding radiation and its impact on occupational and public health. The 1986 Chernobyl accident initiated a major and early increase in childhood thyroid cancer that resulted from ing...
