A comparative assessment of the absorbed doses resulted from computed tomography (CT) examinations, and dose occupational external gamma exposure “Mayak” workers was carried out. The patients’ diagnostic radiation reconstructed using Monte-Carlo simulation on a population 58 virtual adult phantoms across 13 CT protocol categories. Archival records examinations patients were used for reconstruct...

Recent years have seen the increasing use of passive dosemeters that have high sensitivities and, in laboratory conditions, detection limits of <10 µSv. However, in real operational use the detection limits will be markedly higher, because a large fraction of the accrued dose will be due to natural background, and this must be subtracted in order to obtain the desired occupational dose. No matt...

Background: Radiation therapy&nbsp; uses high-energy radiation to kill cancer cells. Photoneutron contamination and induced radioactivity of high energy therapeutic photon beams are considered as the main source of occupational exposure to radiation therapists who works with linear accelerators operating above 10 MV. Materials and Methods: The gamma dose rates were measured after termination of...

INTRODUCTION Although fluoroscopically guided procedures involve a considerably high dose of radiation, few studies have investigated the effects of radiation on medical workers involved in interventional fluoroscopy procedures. Previous research remains in the early stages and has not reached a level comparable with other occupational studies thus far. Furthermore, the study of radiation worke...

BACKGROUND To evaluate the process of a job-specific workers' health surveillance (WHS) in improving occupational health care for construction workers. METHODS From January to July 2012 were 899 bricklayers and supervisors invited for the job-specific WHS at three locations of one occupational health service throughout the Netherlands. The intervention aimed at detecting signs of work-related...

Findings from studies of cigarette smoking and low-dose ionizing radiation exposure and breast cancer are unclear. Laboratory studies indicate that both exposures can cause DNA damage, potentially increasing cancer risk if such mutations occur in growth control genes, such as p53. We examined the potential etiologic heterogeneity of breast cancer by evaluating whether associations between cigar...

BACKGROUND Protection of nuclear medicine unit employees from hazards of the ionizing radiation is a crucial issue of radiation protection services. We aimed to assess the severity of the occupational radiation exposure of technicians performing scintigraphic examinations at the Nuclear Medicine Department, Central Teaching Hospital of Medical University in Lódz, where thousands of different di...

In cases of public or occupational radiation overexposure and eventual radiological accidents, it is important to provide dose assessment, medical triage, diagnoses and treatment to victims. Cytogenetic bio-dosimetry based on scoring of dicentric chromosomal aberrations assay (DCA) is the "gold standard" biotechnology technique for estimating medically relevant radiation doses. Under the auspic...
