Occupational exposure to ionizing radiation can occur in a range of industries, medical institutions, educational and research establishments. Most radiation protection programs, regulations and guidance apply specific restrictions to the occupational exposure of pregnant workers. Both worker and the employer carry responsibility towards safety. The pregnant worker and her conceptus are best protected in a facility that uses best practices for radiation safety. This article reviews was aimed to notify radiology managers and technologists in their management with pregnant workers. The paper describes conceptus doses for worker that are associated with radiology practice, reviews the risks and effects of in utero irradiation, and summarizes the current international and professional organizations policies, guidelines and practical aspects regarding the diagnostic radiologic examinations. Conclusion: careful planning, and minimization of radiation dose by engaging proper radiation safety measures as needed, can allow medical staff to perform duties and normal activities without incurring significant risks to the fetus.

Abstract With the rapid development of nuclear energy, spent fuel will accumulate in large quantities. Spent fuel is generally cooled and placed in a storage pool, and then transported to a reprocessing plant at an appropriate time. Because spent fuel is content with a high level of radiation, spent fuel storage and transportation safety play important roles in the nuclear safety. Radiation dose safety are checked and validated using source analysis and Monte Carlo method to establish a radiation dose rate calculation model for PWR spent fuel storage pool and transport container. The calculation results show that the neutron and photon dose rates decrease exponentially with increase of water level under normal condition of storage pool. The attenuation multiples of neutron and photon dose rates are 4.64 and 1.59, respectively. According to radiation dose levels in different water height situations, spent fuel pool under loss of coolant accident can be divides into five workplaces. They are supervision zone, regular zone, intermittent zone, restricted zone and radiation zone. Under normal condition of transport container, the dose rates at the surface of the container and at a distance of 1 m from the surface are 0.1759 mSv/h and 0.0732 mSv/h, respectively. The dose rates decrease with the increasing radius of break accident, and dose rate at the surface of the transport container is 0.278 mSv/h when the break radius is 20 cm. Transport container conforms to the radiation safety standards of International Atomic Energy Agency (IAEA). This study can provide some reference for radiation safety analysis of spent fuel storage and transportation.

Definition Of

The State Scientific and Technical Center for Nuclear and Radiation Safety (SSTC NRS), a Ukrainian enterprise with a 29-year experience in the area of scientific and technical support to the national nuclear regulator (SNRIU), has been actively involved in international research activities. Participation in the IAEA coordinated research activities is among the SSTC NRS priorities. In the period of 2018–2020, the IAEA accepted four SSTC NRS proposals for participation in respective Coordinated Research Projects (CRPs). These CRPs address scientific and technical issues in different areas such as: 1) performance of probabilistic safety assessment for multi-unit/multi-reactor sites; 2) use of dose projection tools to ensure preparedness and response to nuclear and radiological emergencies; 3) phenomena related to in-vessel melt retention; 4) spent fuel characterization. This article presents a brief overview of the abovementioned projects with definition of scientific contributions by the SSTC NRS (participation in benchmarks, development of methodological documents on implementing research stages and of IAEA technical documents (TECDOC) for demonstration of best practices and results of research carried out by international teams).

Correlational Method

Concerning radiation safety must meet several radiation protection requirements which include justification or utilization of nuclear power, dose limitation, optimization of protection, and radiation safety. The purpose of this study was to determine the optimization of the exposure factor selection and determine the radiation dose received by the patient based on the selection of exposure factors on the thorax examination. The author observed the use of exposure factors on chest radiographic examination with a sample of 60 people. The design of this study uses the correlational method. The independent variables in this study are age, body weight, object thickness, kV, and mAs. Dependent variable exposure to radiation dose on chest examination. The conclusion of this study is the dose exposure level is influenced by age, object thickness, weight, and use of exposure factors which will then be obtained by the DRL (Diagnostic Reference Level) value.

Implementation Of Standards

ABSTRACT In recent years, scholars, journals, and professional organizations in political science have been working to improve research transparency. Although better transparency is a laudable goal, the implementation of standards for reproducibility still leaves much to be desired. This article identifies two practices that political science should adopt to improve research transparency: (1) journals must provide detailed replication guidance and run provided material; and (2) authors must begin their work with replication in mind. We focus on problems that occur when scholars provide research materials to journals for replication, and we outline best practices regarding documentation and code structure for researchers to use.

Harmful Effects

Modern vascular surgeons perform an ever-increasing number of complex endovascular procedures, largely based on patient preference, decreased length of stay, and improved outcome. With the upsurge of endovascular cases, concern has grown regarding the harmful effects of radiation exposure delivered to the patient and the operator. Surgeon education on the appropriate use of fluoroscopic operating factors coupled with appropriate training in radiation safety has been shown to decrease radiation dose. This review elucidates dose terminology and metrics, possible radiation-induced injuries, risk factors for deterministic injury, and radiation safety principles and techniques. Tables provide practical tips to lower patient and operator radiation dose during fluoroscopically guided intervention, and National Council on Radiation Protection & Measurements recommended dose limits for occupational exposure. Figures illustrate reference air kerma, radiation-induced skin injury, effects of image receptor and table position, and operator exposure. This review contains 4 figures, 3 tables, and 53 references.

Careful Planning

Acute traumatic events have the potential to significantly disrupt the learning environment as well as the psychological functioning of students, staff, and the school community. Such events range in size and intensity, though all require careful planning to address the comprehensive safety and recovery needs of a school. Such planning includes considerations of prevention and preparedness, establishing crisis teams and crisis communications, and the selection and delivery of appropriate interventions given demonstrated need. This chapter discusses best practices in school safety planning and approaches to recovery after an incident to address crisis-generated problems, prevent trauma, and help restore the learning environment.
