Le concept de « développement durable » se résume en trois « E » environnement, Energie et Economie. Il a apparu avec les problèmes de changement climatiques et l’épuisement des ressources énergétiques. Il faut trouver un équilibre entre prospérité économique, besoin énergétique et protection de l’environnement pour assurer un développement durable. L’énergie est le cerveau de l’économie mondial et permettant à des nombreuses populations de jouir de confort, de productivité et de mobilité des très hauts niveaux.

Abstract:

Abstract A rapid measurement method for aerosol particle size is required to clarify the formation mechanism of freshly-formed radioactive aerosols in accelerator rooms. A graded screen array (GSA) method only requires brief sampling. Therefore, the GSA method is suitable for the measurement of radioactive aerosols in the accelerator rooms. In this work, a conventional GSA was applied to measure the particle size distribution of an aerosol. An influence of the radioactive gas on the GSA measurement was found. The adsorption of radioactive gases resulted in a discrepancy between the results of

Many countries are currently facing the issue of finding a proper solution to store radioactive wastes coming from nuclear energy production plants. The possibility to store them in underground tunnels is largely considered and investigated. In France, Andra (Agence Nationale pour la gestion des Déchets Radioactifs) selected the Callovo-Oxfordian rock clay (COx) situated in the Meuse/Haute Marne site (France) between 400 and 600 m depth as possible host rock deposit. The excavation of the storage tunnels is expected to create a fractured zone around galleries. However, the factures will be the

Abstract:

Radioactive materials for the medical, technological, and industrial sectors have been effectively regulated in the United States since as early as 1962. The steady increase in the exploration and production of shale gas in recent years has led to concerns about exposures to Naturally Occurring Radioactive Materials (NORM) and Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM) in oil and gas waste streams. This study applied policy surveillance methods to conduct a cross-sectional fifty-state survey of law and regulations of NORM and TENORM waste from oil and gas opera

Abstract Iodine can exist in the form of radioactive and non-radioactive states. Radioactive Iodine-131 (I-131) has been utilized in nuclear facilities. Due to its ability to be absorbed by the thyroid gland, I-131 is used for therapy in thyroid cancer cases. Contrary to the benefit, Iodine is a volatile material that becomes a health problem if humans inhale more than a certain dose under a certain period. Thus, to prevent overexposure to Iodine, all Iodine-related facilities must equip their facilities with Iodine detection systems. The most common radioactive detection system uses an expens

Abstract The amount of radioactive impurities contaminated in the detector gases is required to be kept at a very low level for rare event particle physics such as dark matter and neutrino observation experiments. Zeolite is a well-known class of materials and is one of the possible candidates for removing impurities from gases. At the same time, the amount of radioactive impurities released from the adsorbent material needs to be sufficiently small. In this paper, a development of a new ultralow radioactive zeolite as a product of the selection of ultralow radioactive materials is reported. R

While the presence of uranium in the materials is a necessary condition for the production of Rn-222, the amount of gas emitted by the material depends on other characteristics that allow the migration of the gas.

Radioactive materials which occur naturally and expose people to radiation occur widely, and are known by the acronym 'NORM'.

The earth's crust is radioactive and constantly leaks radon gas into our atmosphere.

However, extreme conditions in these targets present formidable unsolved challenges to efficient production and delivery of RM’s. Here we propose using RFQ gas-reaction cells to produce RM from radioactive ion beams (RIB) by room temperature RIB-gas chemical reactions at eV energies. Two options are possible: (1) using an ion reaction cell (IRC) that is a linear RFQ ion guide and reaction cell used as an ‘on-line ion source’, and (2) using the ARIEL RFQ cooler-buncher (ARQ

Abstract:

Exposure to cigarette smoke has been known to be a major risk factor for lung cancer. Although smoking has long been considered the main cause of lung cancer, about 5 to 25% of lung cancer cases occur in non-smokers. Radon is said to be the second most important cause of lung cancer after smoking. Radon-222 is a chemical element in the form of a highly radioactive gas that comes from the decay of the parent radioactive element, uranium, which is found in the earth's crust. Inhaled radon gas can adhere to the mucosal lining of the airways and damage the airway epithelium. The process of ionizin

The study was carried out by thermodynamic modeling using the TERRA software package in the range from 423 to 2123 K at a constant pressure of 0.1 MPa. Up to a temperature of 623 K, the main components of the gas phase are water vapor, carbon dioxide, methane and hydrogen. Above 1023 K, the gas phase contains predominantly carbon dioxide and monoxide. It was revealed that in the range of 423-923 K uranium is prese

A challenge in many present cutting-edge particle physics experiments is the stringent requirements in terms of radioactive background. In peculiar, the prevention of Radon, a radioactive noble gas, which occurs from ambient air and it is also released by emanation from the omnipresent progenitor Radium. In this paper we review various high-sensitivity Radon detection techniques and approaches, applied in the experiments looking for rare nuclear processes happening at low energies. They allow to identify, quantitatively measure and finally suppress the numerous sources of Radon in the detector

The Need Analysis of Radiation Detection System for Radioactive Materials Out of Regulatory Control. Radioactive materials out of regulatory control (MORC) can threaten human life because they can misuse these materials for terrorism or other illegal acts. Therefore, must prevention of acts of terrorism using radioactive materials by preventing the emergence of MORC itself through nuclear security means, including installing radiation detection systems at borders and entrances to the country's territory. Therefore, it is necessary to know the installation points, and the number of detection de
