Fluoroscopy-guided cardiac electrophysiology procedures are among the most critical x-ray exposures. However, occupational doses still little-known. In this study, an alternative methodology was developed to estimate dose and evaluated its optimization in electro-physiology procedures. The were reproduced by simulation rates of staff measured at chest eyes height through electronic dosimeters. ...

Few therapeutic substances have occupational exposure limits (OELs) set by regulatory bodies and reliance is often placed on in-house OELs derived from a formula based on the therapeutic dose. This mode of derivation relies on assumptions about pharmacokinetics, pharmacodynamics and risk acceptability which might not be soundly based for occupational health purposes. Pharmacodynamic evidence sh...

Introduction: Active personal dosimeters (APDs) are well accepted as useful and reliable instruments for individual dosimetry measurements. APDs have many advantages compared with passive dosimeters for individual external radiation dose assessments. In routine monitoring, occupational exposure is carried out for verification and demonstration of compliance with the regulatory dose limits. So, ...

The concept of biological monitoring (BM) has gained the special interest of individual scientists and international organizations. Today, when analytical problems have almost ceased due to new laboratory techniques and quality assurance systems, the methods for interpretation of results have become the most important issue. There are important discrepancies regarding the role of biological mon...

Nurses make a bureaucracy work on behalf of clients. Occupational health nurses who are already versed in basic concepts applicable to EEOICPA--confidence intervals, occupational histories, exposure assessment, and dose response--can play constructive, caring roles in assisting claimants in securing benefits under this landmark program. Occupational health nurses know that chronically ill emplo...

background and objective: professional radiation workers are occupationally exposed to long-term low levels of ionizing radiation. occupational health hazards from radiation exposure, in a large occupational segment of the population, are of special concern. biological dosimetry can be performed in addition to physical dosimetry with the aim of individual dose assessment and biological effects....

The National Dose Registry (NDR) of Canada is a unique resource for direct estimation of health risks associated with low radiation doses. This is the largest national occupational radiation exposure database, as it includes about 600,000 nuclear, industrial, medical and dental workers exposed to the average cumulative dose of several mSv. Analyses of the NDR data based on a cohort of about 200...
