Maternal acceptability of radiation exposure to children - Relationship with maternal knowledge about radiation exposure influence on children -

The maternal acceptability of radiation exposure to her children was examined and was compared with her knowledge about radiation exposure influence on children to prevent over-care to children. It is thought to be important to prevent excessive confusion or over-care to children due to lack of mother's knowledge and understanding about radiation in the case of nuclear accidents. A questionnaire survey was conducted and the results were tested by Wilcoxon signed rank test. It was found that the degree of knowledge increased the acceptability of the exposure. It leads to the conclusion that providing appropriate information to mothers on radiation exposure to children could improve their self-efficacy regarding care for their children and be effective in preventing over-care.departmental bulletin pape

Determination of lead isotope ratios in rainwater by inductively coupled plasma mass spectrometry

誘導結合プラズマ質量分析計(SHIMADZU ICPM-8500)を用いた降水中のPb同位体比の高精度測定方法と条件を報告する.積分時間は2秒で100回積分を繰り返すことで,精度の良いデータを得ることができ,鉛同位体の標準試料(NIST-SRM 981)の測定値は保証値と一致した.測定値の精度は,鉛濃度が0.5 ppb以上で高いほど良かった.標準試料と未知試料を交互に5回ずつ測定することで,精度の良いデータを得ることができた.Pb同位体比の測定に,内標準元素の添加は影響しないことがわかった.We describe an analytical method on the high-precision determination of lead stable isotope ratios in rainwater samples by inductively coupled plasma mass spectrometry (SHIMADZU ICPM-8500). At a scanning mode, dwell time of 2 s and 100 times of scan gave the best precision to the lead isotope ratio measurements. The analytical lead isotope ratios of the standard reference material for lead isotope (NIST-SRM 981) corresponded with their recommended values. Precision of the measurement was better at a high concentration of lead in sample whose concentration was more than 0.5 ppb. Five times of the set of repeating measurements of the standard and unknown samples gave satisfactory results with good precision level. The analytical results were not affected by the internal standard substance.application/pdfdepartmental bulletin pape
