The terms “atomic law” and “nuclear law” are regularly being (to a certain part as synonyms) used in both scientific and popular literature to refer to a body of legal norms, governing peaceful uses of nuclear energy and ionizing radiation, as provided by sources of international law (“international atomic law,” or “international nuclear law”), national legislation and a complex body of unbinding norms (soft law). Further, several other variations of these terms are also regularly used (such as “atomic energy law,” “nuclear energy law,” “international nuclear law,” “law of the atomic/nuclear energy,” etc.). This contribution aims to identify the origins of this terminological labyrinth and to deal with the perception of these terms in the legal scholarship. Further, this contribution deals with the recent perception of these terms in the legal science of major States, using nuclear energy for peaceful purposes. This article aims to clarify the existing terminology, which is to large extent being used in the literature without an appropriate explanation. The author pleads for a consequent use of the term “nuclear law” (droit nucléaire, yadernoe pravo, Nuklearrecht, derecho nuclear, diritto nucleare) and presents arguments for such conclusion.

Some issues concerning the effect of ionizing radiation on the human body and methodological approaches to the development of radiation safety standards are considered. It is shown that the use of the linear no-threshold hypothesis (LNT hypothesis) in up-to-date radiation safety standards is inconsistent with experimental and epidemiological dose-response data, introduces essential excessive conservatism in the safety assessment process and causes additional problems concerning nuclear power engineering development. Due to the absence of convincing proofs for the existence of the dose threshold* nowadays, it is assumed that any ionizing radiation can lead to a certain risk of developing harmful effects and, therefore, the linear non-threshold dependence between the dose and the probability of the harmful effect is recommended. However, everyone understands that the use of the LNT hypothesis significantly overestimates the real danger. At the same time, the LNT hypothesis aggravates the existing high public fear of nuclear power, and the nuclear power industry pays extraordinary expenses to comply with radiation protection standards based on the LNT hypothesis. In order to comply with rules and regulations based on the LNT hypothesis, the nuclear energy industry invests financial resources in the creation of additional safety barriers for nuclear facilities, as well as new security and control systems. One of the reasons for increasing the cost for construction of a nuclear power plant is the increased design cost caused by enhanced safety requirements that are based on the LNT hypothesis. The traditional engineering approach to ensure the safety of nuclear facilities is based on the increase in the number of protective systems and devices that reduce the probability of severe accidents and reduce the radiation hazard of their consequences. Implementation of this approach in practice leads to a complication and a rise in the price of a nuclear facility. Obviously, it is possible to substantially enhance the safety level of nuclear facilities by creating new and new safety barriers around them, but sooner or later the nuclear energy production will become uncompetitive compared to the generation of other kinds of energy. It is concluded that up-to-date knowledge gives all the necessary grounds for eliminating the use of the linear no-threshold hypothesis and for revising the existing radiation safety standards of Ukraine for some isolated technological operations related to radiation hazardous activities. Such technological operations include activities related to the mitigation of radiation accident consequences, retrieval of nuclear materials and other activities related to the Shelter’s transformation into an environmentally safe system.

Due to difficulties of vegetative propagating of any pants, many tests were performed with ionizing radiation aiming the modification of the characteristics of the plants for obtaining of the improved genotypes and of smaller size. Rootstock “Espada” cultivar, were used to obtain mango seedlings of “Tommy” cultivar. The cuttings were irradiated with different doses of gamma radiation: 0 (control), 2.5, 5.0, 7.5 and 10.0 Gy, in a source of Cobalt-60 type Gammacell-220, installed in the Center for Nuclear Energy in Agriculture, CENA-USP. After irradiation, was performed the grafting type cleft graft. Was made the first evaluation of height of the plants from the budding grafting after 24 months. Data were subjected by statistic program (SAS) and the means were compared by Tukey test (p <0.05). From the results obtained can be concluded that the doses of 2.5 Gy stimulated growth of the plants and the lethal dose was 10.0 Gy because don’t have development of plants.
