knowledge deficiency of work related Radiation Hazards associated with psychological distress among orthopedic surgeons a cross sectional study
Medicine, 2017Co-Authors: Guoxin Fan, Yueye Wang, Changfeng Guo, Xuefeng LeiAbstract:Knowledge and concern degree about work-related Radiation Hazards remained unknown among orthopedic surgeons. The aim of the cross-sectional study is to investigate whether the knowledge degree of work-related Radiation is associated with psychological distress among orthopedic surgeons. This cross-sectional study sent electronic questionnaire via WeChat to orthopedic surgeons nationwide. Concern and knowing degree over Radiation exposure was evaluated by a single self-reported question. Professional evaluation of concern degree was reflected by general psychological distress, which was assessed with the Kessler 10 scale (K10) and depressive symptoms with the Center for Epidemiologic Studies Depression Scale (CES-D). Only 43.23% (115/266) respondents knew well about Radiation and a total of 78.20% (208/266) respondents considered Radiation exposure as a great concern. Among those who reported concerns about Radiation exposure, a total of 57.69% (120/208) respondents reported knowing little about Radiation. Respondents who reported concerns over Radiation exposure were significantly associated with higher scores on CES-D and K10 (P < .05). Among respondents who reported concerns over Radiation exposure, those who have fewer knowledge about Radiation, had higher CES-D and K10 scores than those who knew well about Radiation (P < .05). Among respondents who reported no concerns over Radiation exposure, those who knew little about Radiation still had higher CES-D and K10 scores (P < .05). Fewer Radiation knowledge tends to induce more Radiation concerns associated with higher psychological distress in orthopedic surgeons. Radiation knowledge should be enhanced for surgeons who daily work with Radiation-related fluoroscopy.

The Radiation hazard during space flights
2011Co-Authors: A. V. Kolomenskiy, L. N. Smirennyy, Y. Y. Kovalev, V. M. PetrovAbstract:Galactic cosmic Radiation is described. Distinctive features of Radiation effects in space flights are discussed and space Radiation Hazards are estimated. Measures to provide Radiation safety during space flights are given. The need for safety standards is emphasized.

natural radioactivity in jordanian soil and building materials and the associated Radiation Hazards
Journal of Environmental Radioactivity, 1998Co-Authors: Ahmad N Matiullah, Abdelsalam HusseinAbstract:Natural radioactivity in soil and building materials was determined using gamma spectrometry. Samples were collected from the populated areas of Jordan. 232Th, 226Ra and 40K activities were determined. Soil samples collected from the Jordan valley showed high 40K concentrations which were due to the presence of a potash factory in the valley. One soil sample from southern sector showed very high 226Ra activity (i.e. 774 Bq kg−1). The derived data were compared with the reported data for other countries in the world. Radium-equivalent activities were calculated for soil and building materials to assess the Radiation Hazards. Only one soil sample showed very high Raeq activities (i.e. 979 Bq kg−1). All the other soil samples showed Raeq activities within the limit set by OECD countries (i.e. 370 Bq kg−1). A few marble chips samples also showed Raeq activities greater than the OECD limit. Most of the materials examined are acceptable for use as building materials in accord with the OECD criterion.

Radiation Hazards (RADHAZ) considerations for holographic synthetic phased array sensors
2017 IEEE International Symposium on Antennas and Propagation & USNC URSI National Radio Science Meeting, 2017Co-Authors: E.c. NgaiAbstract:The Holographic Synthetic Phased-Array sensors are robust frontier RF wireless technology. They can be employed on mobile platforms for wide-view and high resolution application. Important concerns are the EMI/EMC and the Radiation Hazards for the deployment of these phased-array sensors.
