New Analytical Science Data Have Been Reported by Researchers at City University of Hong Kong

June 13, 2014

By a News Reporter-Staff News Editor at Science Letter -- Data detailed on Science have been presented. According to news reporting out of Hong Kong, People's Republic of China, by NewsRx editors, research stated, "Computer software for calculation of the sensitivity of a CR-39 detector closed in a diffusion chamber to radon is described in this work. The software consists of two programs, both written in the standard Fortran 90 programming language."

Our news journalists obtained a quote from the research from the City University of Hong Kong, "The physical background and a numerical example are given. Presented software is intended for numerous researches in radon measurement community. Previously published computer programs TRACK_TEST.F90 and TRACK_VISION.F90 [D. Nikezic and K. N. Yu, Comput. Phys. Commun. 174, 160 (2006); 178, 591 (2008)] are used here as subroutines to calculate the track parameters and to determine whether the track is visible or not, based on the incident angle, impact energy, etching conditions, gray level, and visibility criterion. The results obtained by the software, using five different V functions, were compared with the experimental data found in the literature."

According to the news editors, the research concluded: "Application of two functions in this software reproduced experimental data very well, while other three gave lower sensitivity than experiment."
