Abstract

This article presents an interpretation of the US capacity to force North Korea to abandon the development of nuclear weapons, based on the analysis of the conventional balance between the U.S. and North Korea. It is also an attempt to evaluate the impact of the US military transformation on defence policy decisions of the potential opponents of the US. The first (theoretical) part of the article presents the assumptions of theoretical interpretation as well as the fundamentals of evaluating the conventional balance between the US and North Korea. The second part of the article highlights the key moments of the US and the international community’s so far unsuccessful attempts to force North Korea to give up its nuclear weapons and explains the reasons for such unsuccessful policy. The third part of this paper analyzes the conventional balance between the US and North Korea, taking into account the conventional forces of those countries, their long range conventional strike programmes as well as the missile defence programmss - this analysis presupposes the failure of the US to prevent North Korea from nuclear weapon development

Abstract

The area of interests of nuclear physics are studies of reactions, wherein atomic nuclei of projectile collide with target nuclei. An amount of energy lost by projectile nucleus during its passing through the target is a major issue – it is important to know how charged particles interact with matter. It is possible to afford this knowledge by using theoretical programs that calculate energy loss applying the Bethe-Bloch equation. Hadrontherapy, which is a field of still growing interest, is based on the interactions of charged particles with matter. Therefore, there exists a need of creating a simple model that could be used to the calculation of dose distributions in biological matter. Two programs (SRIM, Xeloss), used to the calculation of energy loss by nuclear physicist, have been adapted to determine the dose distributions in analogues of human tissues. Results of the calculations with those programs for beams used in hadrontherapy (e.g. 1H, 12C) will be compared with experimental data available in references.

Abstract

A nationwide survey was conducted in 2014 to investigate environmental outdoor radon level in 33 provincial cities across China. The radon detector used was a passive-type solid-state nuclear track detector, CR-39. Measurements were conducted under the same condition following the quality control programme. Outdoor radon concentrations in China ranged from 3 to 30.0 Bq·m−3. The annual arithmetic and geometric mean radon concentration were 14 and 13.2 Bq·m−3, respectively. The radon concentrations in the locations near or along coastline were lower than the average value, while those located in the inland area were higher. As a whole, the result showed no big difference from the data measured during the period 1983–1998. It demonstrated that the outdoor radon concentration level in China has not been changing remarkably for 20 years.
