“Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less”
Owing to the great work by several Physicists, it is worthwhile to appreciate the efforts made by them in discovering the radiations. The credit goes to several pioneers in the field of radiation science such as Wilhelm Conrad Roentgen, Henry Becquerel, Marie Curie, and many more. Radiation has a profusion of applications in several fields of science and technology highlighting every walks of human life. Agriculture, Industry, Medicine, Aerospace, Food Processing, and Nuclear Power are some of the areas to mention where radiations are being used. Hence, it is necessary to understand the origin, properties, and effects of these radiations on the medium which results in physical, chemical, and biological effects. Hence, there is a need for understanding the effect of these radiations. In addition, there are several situations in which the human beings come in contact with the radiations mainly in research, medical, industries, nuclear power plants, agriculture, and spacecraft applications. Safety use and control of radiations are very essential for the personnel involved in these fields. Hence, it is standard practice for the radiation workers to optimize the radiation exposure as low as reasonably achievable. In view of this, Department of Physics, Bangalore University, Bengaluru, in collaboration with AMD, Bengaluru, had organized a 2-day National Conference on Radiation Physics (NCRP-2017) during November 23 and 24, 2017, to understand the latest developments in the field of radiation physics and to exchange the same among the scientists/professional/researchers.
The scientific program of the conference included invited talks and contributory papers in the form of oral and poster presentations under the thematic areas Radiation Detection and Measurement, Radiation Physics and Interaction in Matter, Biological Effects of Radiation, Radiation Processes and Transport, Applications of Radiation and Radioisotopes in Agriculture, Medicine, Food Processing, and Industry, Radiation for society, Environmental Radioactivity, Radiation Protection and Dosimetry, Reactor Physics and Shielding, Nuclear Energy and Materials, Radiation in Space Science Studies, Materials Processing with Ion Beams, Electron, Gamma, and Neutrons, Effects of Radiation on Materials, Advances in Defects and Material Characterization, and Radiation Awareness Program. The NCRP-2017 had received very good response with nearly 85 contributory papers from different parts of the country and acknowledged for their contribution, of which few papers have been selected and being published in RPE Journal (in this issue).
This issue comprising 11 articles mainly deals with the distribution of various radioactive nuclides in different regions and assessment of the radiation dose to the public. This kind of study serves as baseline data which help in the expansion of nuclear power plants. In this regard, there is an interesting contribution by Vijay Kumar et al., where the paper discusses the spatial distribution of fall out 137 Cs in the marine environment of Kudankulam. The observed 137 Cs activity is compared with other Indian and Asia-Pacific marine radioactivity database and has been concluded that no other contribution apart from the fallout. A new attempt has been made by Gladys Mathew et al., in understanding the leaching of uranium from bedrock to groundwater in the northeastern part of Bengaluru city as a case study and has observed the strong correlation between the two. In another paper, the concentration of tritium in ambient air around Kaiga Nuclear Power Plant was measured by Srinivas Kamath et al., and the results are comparable with those reported for other nuclear power plants in India and other parts of the world.
Mr. Charan Kumar et al. attempted to analyze the possible periodicity (or memory) from the time series data on radon activity, collected at the National Atmospheric Research Laboratory, Gadanki, near Tirupati. It was concluded that the time evolution of precipitation shows that 20% of the average monthly radon concentration can be attributed to nonlocal effects. In another paper, Mr. Karthik Kumar et al. have studied the influence of moisture content on radon/thoron exhalation rate.
It is a challenging task to identify the exact concentration of uranium ore underneath the earth's crust. In this view, one of the articles by Madhavi et al. explained the varied concentration of Uranium ore in diverse geographical domains such as rocks, soils, rivers, and oceans from Rasimalai and Pakkanadu areas of Tamil Nadu. This study reports that syenite and pyroxenite with carbonatite veins host the major portion of uranium deposition in the study area.
Overall, this issue would certainly find interesting and provide quality information to the researchers working in the field of environmental radioactivity and also serves as a database to set up several nuclear power plants in the future in different parts of the country. I wholeheartedly compliment the researchers for their involvement and commitment toward their respective work and contributing to the RPE Journal. I also express my sincere gratitude to RPE for providing an opportunity to publish the research articles in this esteemed journal.
