abstract background: monitoring internal exposure of individuals handling significant amounts of iodine-125 (i-125) for iodination is of great importance. these individuals are potentially exposed to external contamination, and internal contamination through inhalation, ingestion and intact skin absorption, to i-125. considering radiological toxicity of this radionuclide its monitoring in the w...

Most of the population living in areas close to the Chernobyl accident have been exposed to external and internal low doses of ionising radiation. High doses effects are well known, however low dose radiations had not been yet investigated. The aim of this work was to investigate the cognitive effects of internal low doses ionising radiation. We evaluate the behaviour in mice pups after that pr...

OBJECTIVE To discuss the basic concepts involved in the development of yttrium 90 (Y-90) microsphere selective internal radiation treatment and review the clinical data pertaining to its application in hepatic colorectal cancer metastases. DATA SOURCES Published studies and scientific paper presentations. STUDY SELECTION Randomized clinical studies and retrospective reviews. CONCLUSIONS S...

With increasing evidence, internal radiation therapy, also known as brachytherapy, has become a neglected aspect of nuclear medicine in the molecular era. In this paper, recent developments regarding internal radiation therapy, including developments in radioiodine-131 ((131)I) and thyroid, radioimmunotherapy (RIT) for non-Hodgkin lymphoma (NHL), and radiopharmaceuticals for bone metastases. Re...

Preferentially delivering ionizing radiation to target tissues during radiotherapy procedures is investigated using internal radiation-generating devices and microspheres loaded with radioactive material. This chapter presumes the existence of internal radiation-generating devices and develops their requisite characteristics to permit the selective irradiation of tumors. The feasibility of disr...

Background: Ionizing radiation is present in all environment of the Earth’s surface, beneath the Earth and in the atmosphere. Human beings are exposed to external radiation from their surroundings naturally and also to internal radiation from food, water and air they consume. Then, it is important to measure and develop knowledge about radiation. Objective: This study is designed to evalu...

Internal modes of vector solitons and their radiation-induced damping are studied analytically and numerically in the framework of coupled nonlinear Schrödinger equations. Bifurcations of internal modes from the integrable systems are analyzed, and the region of their existence in the parameter space of vector solitons is determined. In addition, radiation-induced decay of internal oscillations...

most popular sources for electromagnetic waves. however, there are many concerns regarding their biological effects on the body, especially the central nervous system. therefore, the aim of this study was to evaluate the effects of cell phone radiation on histology of the cerebellar granular cells in the neonatal rat. materials and methods: we selected some wistar rats. then, we randomly divide...
