Critical analysis and suggestions to improve the existing system of radiation control in X-ray rooms

This paper demonstrates the shortcomings of the existing method of radiation control in the X-ray rooms and the interpretation of the results of the measurements to assess the compliance of the working conditions of various groups of exposed individuals with radiation safety requirements. A new method of interpretation of the measurement results is proposed, considering the relative time spent by certain categories of exposed persons in the corresponding rooms during the use of the X-ray units, as well as the use of personal protective equipment (lead aprons). The interpretation of the measurement results in the treatment room according to the new approach has demonstrated the compliance of the working conditions to the Norms and Rules of radiation safety, provided that the worker is wearing a protective apron. The proposed approach to the interpretation of the results of the measurements in adjacent rooms leads to both reduced and stricter requirements for the stationary shielding. The paper includes a special focus on the incorrect calculation of stationary shielding for the installation of several X-ray units in one X-ray room within the framework of the current approach.

Special Precaution

An incident beam X-ray collimator for Mao-Bell type diamond anvil cell (DAC) has been developed. Alignment of the collimator is carried out in situ while viewing the image of the collimated X-ray spot formed on a thin layer of fluorescent material spread on the diamond anvil culets with the help of a microscope. Special precaution has been taken to meet the radiation safety requirements during alignment and routine use. This collimator is of immense help for laboratory based high pressure X-ray diffraction experiments.

Material Choice

A study of metallic brazing material for internally cooled optics is presented. The study shows the influence of the different material properties on the final quality of the bond in terms of diffracted wavefront distortion,i.e.enlargement of the rocking curve. By choosing the proper brazing material and applying the proper brazing conditions, the influence of the brazing material can be fully eliminated. Furthermore the degradation of some brazing material due to the extreme working conditions of the optics is presented. Measurement results from ESRF and KEK confirm the importance of the proper brazing material choice.

This study is focused on the main activities on provision of the radiation safety as a part of sanitary surveillance and radiation terrorism counteraction during the 2018 World Football Championship. The main activities at the preparatory stage are collection and analysis of information on the potentially dangerous sources of ionizing radiation in the regions of the Russian Federation hosting the 2018 World Football Championship; control of compliance to the sanitary rules of the projects of the allocation of X-ray screening units and their commissioning; radiation control as a part of the commissioning of the sport facilities after construction/reconstruction; sanitary control of the allocation of X-ray screening units on the sport and infrastructure facilities; organization-methodical activities. During the World Football Championship it is planned to carry out the radiation control in monitoring points and the control of the concentration of radionuclides in water and food stuff samples. In the framework of the radiation terrorism countermeasures, the main activities of the provision of the radiation safety are the radiation control on the infrastructure facilities, remote points of inspection and entry points to the sport facilities; full-time emergency preparedness. A brief evaluation of the equipment of the Rospotrebnadzor radiation control laboratories in the regions of the Russian Federation hosting the 2018 World Football Championship and their preparedness for the provision of the radiation safety is also presented in the paper.

National Disaster

Introduction: WHO has declared coronavirus disease 2019 (COVID-19) a global pandemic. The Indonesian government stated that COVID-19 was a national disaster. Objective: Conduct a radiation exposure examination for the workplace area around the isolation room for COVID-19 at Kerawang Hospital. This examination ensures radiation safety, which is then used as an evaluation material to improve radiation safety. Methods: Descriptive study with direct measurements in the COVID-19 isolation room with measurement points in several treatment rooms frequently examined chest X-rays. Calculation of the exposure test by calculating the measured value minus the background value then multiplying the calibration factor. Results and Discussion: Measurement of radiation exposure test was carried out in 3 locations, namely in the emergency covid x-ray room, room 107, and room 112. The measurement results from the emergency COVID-19 x-ray room showed that the exposure to the parking area was 0.13 μSv. Measurements from room 107 obtained exposure in the changing room for nurses of 0.113 μSv / h, Nurse Station of 0.063 μSv / h, and the doctor’s room of 0.149 μSv /h. For measurements from room 112, radiation exposure in the anteroom room was 0.205 μSv /h, Nurse Station was 0.123 μSv /h, and the doctor’s room was 0.183 μSv /h. Thus, the radiation exposure tests in several locations in the COVID-19 isolation room at the Karawang Hospital were below 0.25 μSv /h for the general public or were declared safe. Conclusions and suggestions: The results of radiation exposure tests in several locations of the COVID-19 isolation room at Karawang Hospital are still within safe limits, carried out to provide safety and comfort for doctors and paramedics working in their respective workspaces and working in the covid room area both in terms of safety in dealing with patients or from radiation safety.

Final Rule

Abstract Animal disease traceability—or knowing where diseased and at-risk animals are, where they’ve been, and when—is important to ensuring a rapid response when animal disease events take place. Although animal disease traceability does not prevent disease, an efficient and accurate traceability system reduces the number of animals and response time involved in a disease investigation; which, in turn, reduces the economic impact on owners and affected communities. The current approach to traceability in the United States is the result of significant discussion and compromise. Federal policy regarding traceability has been amended several times over the past decade based on stakeholder feedback, particularly from the cattle industry. In early 2010, USDA announced a new approach for responding to and controlling animal diseases, referred to as the ADT framework. USDA published a proposed rule, “Traceability for Livestock Moving Interstate,” on August 11, 2011, and the final rule on January 9, 2013. Under the final rule, unless specifically exempted, livestock moved interstate must be officially identified and accompanied by an interstate certificate of veterinary inspection (ICVI) or other documentation. However, these requirements do not apply to all cattle. Beef cattle under 18 months of age, unless they are moved interstate for shows, exhibitions, rodeos, or recreational events, are exempt from the official identification requirement in this rule. We can do better. Our industry must recognize how vulnerable we really are, should we be subject to a disease such as foot and mouth. We must also understand what a competitive disadvantage the United States faces in the global marketplace without a recognized, industry-wide traceability system.
