NEW DETERMINATION METHOD OF RADON-220 IN MINERAL SPRINGS BY EXTRACTION-LIQUID SCINTILLATION COUNTER
Authors: Horiuchi Kimiko , Murakami Yukio 
Published: July 2006

Abstract
220Rn in mineral springs was extracted into toluene. The α and β or γ rays spectra of 220Rn and its descendants in toluene were measured by LSC or γ spectrometer and the establishment of equilibrium between 212Pb and its descendants was confirmed. Based on this fact a new determination method of 220Rn is developed, consisting of the extraction of radon and the application of integral counting with LSC to 212Pb in radioactive equilibrium with the descendants.

Authors: Nakashima Hiroshi , Okamoto Katsunobu 
Published: July 2006

Abstract
A correlation between the bond scission in mass spectra and the change of electron density on the skeletal bonds from molecules to molecular ions was examined, and it showed that the scission probability of the bond was closely related to the decrease of electron density forming the bonds. This method was applied to several alkylamines.

Authors: Takamuku Setsuo , Kigawa Hitoshi , Miki Sigeo , Sakurai Hiroshi 
Published: July 2006

Abstract
γ-Radiolysis of tetraphenylcyclobutane(TPCB) in HMPA forms trans-stilbene (t-St) preferentially. The effect of an additive proved that the cycloreversion of TPCB occurs mainly by the reaction of solvated electrons with TPCB. Absorption spectra of γ-irradiated TPCB solution in MTHF show that dissociative electron capture proceeds even at 77K with a predominant steric retention leading to t-St and t-St\ewdot.

Abstract
