The advances in digital imaging and the improvement in interventional tools and devices like catheters and stents have expanded the use of interventional procedures. During the period 1998-2008, the total number of interventional procedures increased by 78% [1]. Interventional radiology [IR] and cardiology [IC] procedures deliver high radiation doses both to patients and medical personnel, whic...

BACKGROUND CONTEXT Low back pain (LBP) is a widespread musculoskeletal condition that frequently occurs in the working-age population. Numerous occupational physical activities have been implicated in its etiology. PURPOSE To conduct a systematic review establishing a causal relationship between occupational standing or walking and LBP. STUDY DESIGN Systematic review of the literature. SA...

Dermal uptake of chemicals at the workplace may contribute considerably to the total internal exposure and so needs to be regulated. At present only qualitative warning signs--the "skin notations"--are available as instruments. An attempt was made to develop a quantitative dermal occupational exposure limit (DOEL) complementary to respiratory occupational exposure limits (OELs). The DOEL refers...

Background. In a French large population-based case-control study we investigated the dose-response relationship between lung cancer and occupational exposure to diesel motor exhaust (DME), taking into account asbestos exposure. Methods. Exposure to DME was assessed by questionnaire. Asbestos was taken into account through a global indicator of exposure to occupational carcinogens or by a speci...

The Nuclear Regulatory Commission is amending its regulations to make minor corrections and clarifying changes to the NRC's 10 CFR Part 20, "Standards for Protection Against Radiation." The final rule is also intended to conform other regulations with the Commission's 1991 revised radiation protection requirements. In addition, the final rule includes a minor policy change that raises the monit...

The occupational annual dose levels, encountered at fabrication of emerging nuclear fuels, have been studied. Emerging fuels for the single and multiple recycling of Pu and MA have resulted in considerably higher gamma and neutron doses in comparison with commercial fuels. The occupational dose limit is exceeded at fabrication by a single fuel rod in all fuel cases with (241)Am and Cm isotopes ...

background: ˝radioadaptive response˝ is well-documented phenomenon appeared in low dose ionizing radiation received in vitro and in vivo. occupational exposure has always been a great concern for radiation workers therefore this study was performed to study radioadaptive response in terms of residual dna double strand breaks as an endpoint in peripheral blood leukocytes of occupationally expose...

A recently developed active electronic personal dosemeter (AEPD) was utilised in order to measure the levels and the structure of occupational exposure to scattered X-ray radiation of medical staff who performed percutaneous revascularisation therapy that involves interventional radiology (IR) on the pelvis and upper leg arteries. The AEPDs, placed on the operators' and assistants' chests, that...
