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...

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...

The research objective is assessment of structural genomic damages in plutonium workers. The study group included workers of the Mayak Production Association subjected to chronic occupational internal exposure to incorporated Pu and/or external γ-rays. A lymphocyte culture of peripheral blood was chosen as an object of study. The yield of intrachromosomal exchange aberrations of chromosomal typ...

Introduction: Although travertine is now widely used as a building material, the effects of its radiological hazards to public health should be a matter of concern. Therefore, this study aimed to determine its radiological parameters with regard to human health. Material and Methods: In this research 10 travertine samples were collected ...

OBJECTIVES To implement a new cost efficacy internal Service for blood component irradiation, we carried out specific procedures and quality assurance reports using the linear accelerators (LINACs) of the Regina Elena Institute (IRE) Radiotherapy Department instead of a dedicated device. METHODS The technical aspects, quality assurance and regulatory requirements of the internal procedure to ...

A single dose of radioactive copper ((64)Cu or new Cu) was infused into the stomach of rainbow trout (Oncorhynchus mykiss) to model dietary copper (Cu) uptake under conditions of a normal nutritional dose and optimum environmental temperature (16 degrees C, 0.117 microg Cu g(-)(1 )body mass). The distribution of new Cu to the gut and internal organs occurred in two phases: rapid uptake by the g...

introduction:  skin  sparing  is  one  of  the  most  desirable  characteristics  of  high  energy  photon  beams. however, the photons emerging from the target of linacs are contaminated by secondary  electrons  as  a  result  of  their  interactions  with  air,  collimators,  flattening  filter  and  any  other  objects in their path. this phenomenon tends to increase the skin dose received b...

introduction: the aim of present study was to estimate effective dose from most common procedures performed in nuclear medicine departments of golestan province. methods: data of nuclear medicine procedures performed in 2 nuclear medicine departments in golestan province were collected during 4 years. effective dose, collective effective dose and effective dose per examination were calculated u...

The need for harmonization of the procedures for internal dose assessment has been formulated within an EU research project under the 5 Framework Program. The aim of the project IDEAS (partly funded by the European Commission under Contract No FIKR-CT2001-00160) has been to develop general guidelines for standardizing assessments of intakes and internal doses. The IDEAS project started in Octob...
