JOURNAL FREE ACCESSThe dose absorbed in an organ due to external radiation depends on the photon energy and incident direction to the body. The results of organ absorbed dose measured by C. ZEOW et al. were revised into the absorbed dose in the organ per unit exposure (rad/R); these values are tabulated for each organ, photon energy and incident direction to the body.
The gonadal doses are compared with those reported by other workers in energy dependence at a typical incident direction, and problems in conversion factor (rad/R) to the organ dose are described.
The results for the testes agree with those by other workers for anterior and horizontal rotational irradiations. There is disagreement, however, for posterior and left-side irradiations. This may be due to the differences in shape of the phantom and position of the organ. On the other hand, the ovary dose for all the incident directions is in good agreement with that by other workers.View full abstractDownload PDF (879K) -
Influence of Main Cations in Ground Water on the Distribution Coefficients of Radioactive Cations to Ion ExchangersTenson TSUTSUI, Kenzo NISHIMAKI1975 Volume 10 Issue 4 Pages 203-210

JOURNAL FREE ACCESSThe adsorption of radioactive cations to clay minerals, which governs the movement of radioactive cations through the saturated zone, has been investigated.
The ion exchange capacities of Amberlite IR-120B, Green Sand and KUR Sand were measured for NH4+, Ca2+, Mg2+, Na+ and Cs-. The results showed that the capacities of these ion exchangers were not changed with the kinds of cations examined. The distribution coefficients (KdA for x) of each radioactive cation (22Na, 137Cs, 54Mn, 60Co, 65Zn, 85Sr and 133Ba) to the ion exchangers saturated with Ca2+, Mg2+ or Na+ were obtained for the several concentrations (Cx) of the corresponding cations. The following empirical equation was derived from the above results.
KdA for x=mx (Cx)-nx
Influence of the presence of Ca2+, Mg2+ and Na+ were discussed using the values of mx and nx.
It can be concluded that Ca2+ and Mg2+ influence largely on the adsorption of radioactive cationsin the saturated zone.View full abstractDownload PDF (807K) -

ROOT VEGETABLE CONSUMPTION IN KUJI TOWN AND TOKAI VILLAGEMisako SUMIYA, Yoichiro OHMOMO1975 Volume 10 Issue 4 Pages 215-219

JOURNAL FREE ACCESSThe consumption of starchy and non-starchy roots of root vegetables was surveyed on three kinds of families in Kuji town and Tokai village. The average daily intake of starchy and nonstarchy roots through a year was 28-43g/d/p and 65-95g/d/p, respectively. Seasonal variation was observed for non-starchy roots, namely high consumption in autumn and less in summer. The contribution of starchy roots consumption was only 10 percents to the whole vegetable consumption.View full abstractDownload PDF (340K) -
