Aims. The primary objective of this study was to estimate the absorbed dose rate of the naturally occurring radioactive nuclides at a height of one meter above earth's surface. Methods. The outdoor radiation exposure dose rates caused by radioactivity concentrations of radionuclides in the soil have been evaluated at several locations in Awjilah and Jalu, Libya, using portable devices RADEX RD 1501 and LB 123. Results. Thirty-seven random sites were examined. The absorbed dosage rate ranged from 34.8357 to 95.7734 nGy/hr in dry air at a he

The study of natural background radiation dose at thirty two locations of Kathmandu valley has been done successfully using the instrument Radalert 100. The average dose rates and annual effective dose were measured. From the measurements, the least value of average dose rate was found to be (22.3±3.9)×10-3 mR/hr for Sundhara and the greatest value of average dose rate was found to be (37.7±7)×10-3 mR/hr for Budhanilkantha 3. As per the annual effective dose, the least value was 0.391 mSv/yr for Sundhara and the greatest value was 0.661 mSv/yr for Budhanilkantha 3. The average annual effective

Abstract This study aims to evaluate patient radiation dose during fluoroscopically guided endovascular aneurysm repair (EVAR) procedures. Fluoroscopy time (FT) and kerma-area product (KAP) were recorded from 87 patients that underwent EVAR procedures with a mobile C-arm fluoroscopy system. Effective dose (ED) and organs’ doses were calculated utilising appropriate conversion coefficients based on the recorded KAP values. Entrance surface dose (ESD) was calculated based on KAP values and technical parameters. The mean FT was 22.7 min (range 6.4–76.8 min), resulting in a mean KAP of 36.6 Gy cm2

IntroductionThe purpose of this two--folded quantitative study was to determine the radiation doses received by staff during 2014 at the PET--department at St. Olavs Hospital in Trondheim, Norway. Although studies show that the doses received by staff performing such examinations are far beneath the limits set by regulation, there was a need to determine how much radiation the staff at this clinic actually was exposed to. We investigated in detail both dose rates emitted by 18 F from different parts of the body to the surroundings along with effective doses to staff during 2014.MethodPart one

The contribution to the effective dose from cosmic radiation of the Earth’s radiation belts, galactic cosmic rays, and solar proton events for astronauts located in the large-diameter working compartment of the service module of the ISS is considered. It is shown that for quasi-stationary sources of cosmic radiation, a change in the orbital inclination of 51.6° by 97.0° does not lead to significant variations in the average daily effective dose rate. When considering the contribution to the effective dose from solar-flare protons, the dose load on astronauts can increase by ten or more times.

This occurs because the average worker does not prepare adequately for retirement. This transcends to Ghana where most people work in the informal sector. Hence, there is a need to develop strategies that would help people live comfortably in their old age when they can no longer work.

Abstract We have developed a unique technology for mutation induction of plants using energetic ion beams at the RI Beam Factory (RIBF) of Rikagaku Kenkyūjo (RIKEN) (Institute of Physical and Chemical Research). Ion beams effectively induce mutations at relatively low doses without severely inhibiting growth. The irradiation treatment can be given to various plant materials and mutation can be induced in a short time, between seconds and a few minutes. The linear energy transfer (LET) of ions depends on the nuclide and velocity. Since LET value affects the mutation frequency, it is an importan

Introduction: 3,4-dihydroxy-L-phenylalanine (L-dopa) is the gold standard drug for the treatment of Parkinson’s disease (PD). This disease causes degeneration of dopaminergic cells, L-dopa supplies the lack of dopamine, being effective in its treatment. The average time for the onset of this hyperkinetic disorder is usually 6.5 years and the young age at the beginning of the disease. This pathology may present with chorea, dystonia, myoclonus and stereotypes. Diskinesia-inducing L-dopa (LID) remains one of the most challenging unmet needs in the treatment of PD and other neurodegenerative dise

This paper describes the cooperation and inspection arrangements for verifying the dismantlement of non-strategic Russian submarines, including waste handling, in accordance with the provisions given in the bilateral agreement between the Governments of Russia and Norway and the Norwegian Plan of Action for Nuclear Safety. The main concerns during the project implementation are nuclear safety, the individual safety of workers and the safe and secure handling of radioactive and toxic wastes. Based on data provided by the shipyard on individual exposure, one dismantlement project results in aver

The availability of numerous beneficial healthcare technologies presents both an opportunity and a challenge: while they have the potential to improve health outcomes, financial constraints limit their widespread adoption. This challenge is further exacerbated by an aging population and shifting epidemiological trends, which place increasing pressure on global healthcare expenditures. To ensure that rising healthcare costs translate into meaningful improvements in population health, it is essential that spending remains sustainable, does not displace other critical investments, and aligns with

The COVID-19 pandemic led to declines in in-person consultations and substantial increases in telemedicine use in many countries. This paper investigates whether this pattern occurred in Colombia using data for people with particular health conditions prior to the pandemic (rheumatoid arthritis, hemophilia, chronic kidney disease, HIV, and cancer). The study shows that healthcare utilization by people in Colombia with these conditions dropped significantly during the first months of the pandemic relative to the average of the previous two years. However, by the end of 2020, the rate of healthc

The objectives of this project were to predict the performance of naturally and fan-ventilated greenhouses as a function of climate, type of crop, evaporative cooling and greenhouse size, and to estimate the effects of the two cooling systems on yield, quality and disease development in the different crops under study. Background In the competitive field of greenhouse cultivation, growers and designers in both the US and Israel are repeatedly forced to choose between naturally ventilated (NV) and fan ventilated (FV) cooling systems as they expand their ranges in an effort to remain profitable.

Amid the rising climate change concerns, California enacted Senate Bill 375 (SB 375) to tackle transportation greenhouse gas (GHG) emissions. SB 375 requires Metropolitan Planning Organizations (MPOs) to develop a Sustainable Communities Strategy (SCS), a regional transportation and land use vision plan, to reduce GHG emissions. Meanwhile, a local government can develop a Climate Action Plan (CAP), a non-binding, voluntary plan to reduce GHG emissions that may align with the regional SCS. Recent progress reports indicate California is not making sufficient progress to meet SB 375 emissions red

This paper proposes an innovative steel interlocking tie system for composite walls in reinforced concrete Modular Integrated Construction (MiC), eliminating the need for tie bolts penetrating precast sidewalls. This design facilitates complete factory interior fitting and minimizes on-site disruption to internal finishes. Experimental tests for the proposed steel interlocking system have been conducted and the advanced finite element models for the investigation of the system have been developed. Six case studies comparing density-based topology optimization and empirical optimization using f
