Radiation dosimetry in protection against ionising radiation involves research of all possible pathways through which natural or man-made radioactive materials can contaminate a habitat and actually harm its biota. It also takes into account natural and artificial (man-made) electromagnetic ionizing radiation (gamma and x radiation). This article presents a dosimetric study assessing exposure t...

Abstract Introduction: not following safety tips during mobile radiography can bring about risks for nurses in ICU wards. Objective: the study aimed to determine the status of personal protection against radiation and its associated factors in nurses working in ICU wards of health care-educational centers affiliated with Guilan University of Medical Sciences in Rasht, Iran. Materials and Met...

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:  the aim of the study was to estimate the radiation dose during emergency exposure to patients treated with iodine-131 during the isolation period. materials and methods: the dose rate from a sample of 192 patients administrated by three different radioactivity of 131i (3.7, 5.55 and 7.4 gbq) was measured, at 1 meter after 1, 24 and 48 hours post dose administration, at three differ...

This study presents the summary of historical exposures, measurement practice and evolution of the recording of the individual doses of medical radiation workers during 1950–2003 in Lithuania. The aim of this study is to present occupational exposure of medical radiation workers in Lithuania since the earliest appearance period. Data from publications have been used for the earliest two periods...

Systematic biological measurement of "cytogenetic endpoints" has helped phenomenally in assessment of risks associated with radiation exposure. There has been a surge in recent times for the usage of radioactive materials in health care, agriculture, industrial, and nuclear power sectors. The likelihood of radiation exposure from accidental or occupational means is always higher in an overburde...

Ultrasounds and ionizing radiation are extensively used for diagnostic applications in the cardiology clinical practice. This paper reviewed the available information on occupational risk of the cardiologists who perform, every day, cardiac imaging procedures. At the moment, there are no consistent evidence that exposure to medical ultrasound is capable of inducing genetic effects, and represen...

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...

this study aimed to evaluate the radiation safety condition and the level of radiation-awareness amongst staff and patients in 18 hospitals of shahid beheshti university of medical sciences, tehran, iran. this descriptive, cross–sectional study was administered to patients and personnel, also making a review on the radiation-safety status in the hospitals. in evaluating the level of awareness, ...
