This book was released on 2017-01-26 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation, "Development of the Customized Radon Detector and Studies of the Radon Background Onsite for the Daya Bay Reactor Neutrino Experiment" by Kar-yee, Leung, 梁嘉怡, was obtained from The University of Hong Kong (Pokfulam, Hong Kong) and is being sold pursuant to Creative Commons: Attribution 3.0 Hong Kong License.

Abstract: The goal of the Daya Bay Reactor Neutrino Experiment is to determine the last unknown neutrino mixing angle θ13, in sin22θ13 to sensitivity better than 0.01 at 90% confidential level in three years of running. In order to reach the goal, background from natural radiation should be controlled less than 50 Hz, accordingly radon, which is a naturally-occurring radioactive gas, is one of the factors need to be monitored. A High-sensitivity and High-reliability Hong Kong (H3) radon monitoring system is developed to support the slow control system of the experiment. It achieves the sensitivity requirement and fulfills the data acquisition specification by using an enlarged sample chamber, an improved electronic and a designed software, in addition to the dehumidifier system for long term use. Four final products of the radon detector were well calibrated and tested before application; the sensitivities of counted progenies Po-218 and Po-214 are 3.65 0.37 x10-2 cpm/Bq-m3 (C.F.is 27.42.7 Bq/m3/cpm) and 3.94 0.40 x10-2 cpm/Bq-m3 (C.F. is 25.42.5 Bq/m3/cpm). Its performance is the highest among the same type of commercial available products. This radon monitoring system has been successfully taking data as the background measurement of the experiment for more than half a year, and will continue to provide useful information for the following several years. From the results, the radon levels in the air in Experimental Halls and in the water of water systems were higher than expected, but still at the acceptable levels. Further works have to be done to control them at preferred levels. DOI: 10.5353/th_b5053415 Subjects: Radon measures

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the meeting was to bring together a number of scientists active in the development and use of passive radon monitoring instrumentation, primarily activated charcoal detectors and alpha track detectors. Many of those present expressed a desire to receive copies of the viewgraphs and other materials presented. Most have supplied extended abstracts or complete reports. These materials are reproduced here as a Technical Measurements Center Report for the benefit of those attending the meeting and for others interested in passive radon monitoring. Individual papers were processed separately for the data base.
