Times Cited Count：5 Percentile：37.23(Physics, Multidisciplinary)Muon spin relaxation measurements were performed on a = 1 of composite Haldane spin chains in IPA-CuCl. At a zero external magnetic field, the muon spin relaxation became slightly faster with the development of a magnetic short-range order, but, as expected, oscillating spectra, which indicate a magnetic long-range order, did not appear. The appearance of the local field at a temperature between 12 and 2.0 K may suggest experimental evidence of the crossover from = 1/2 spin state to = 1 of composite Haldane spin state with decreasing temperature.

The amount of hydrogen produced in 
-radiolysis of mixture of seawater and mordenite was studied. The measured yield was decreased with decrease in the weight fraction of seawater. However, the yield was not simply proportional to the weight fraction of seawater and the influence of the mordenite was observed as additional production of hydrogen. At a weight fraction of seawater more than 0.2, the measured amount of hydrogen could be explained by an empirical equation given by a liner combination of two hydrogen production terms representing hydrogen production due to the energy deposition to seawater and that to mordenite. Each of the terms was expressed as a product of the absorbed energy and a yield given as the proportionality coefficient, and each of the yields could be a constant independent of the mixture ratio. The result imply an instinctive explanation of hydrogen production from the mixture of solid and liquid using the two respective yields.

Task Group of Low dose and Low Dose Rate Radiation Risk Estimation Method in the Japan Health Physics Society presented the task group activity from April, 2016 to March, 2018. The presenter introduce the current status and issues of dose assessment (e.g. effects of anatomical characteristics of subjects, monitoring data, distribution of dose and dose rate in body on uncertainty of dose assessment).
