Test of internal - conversion theory with measurements in 134 Cs and 137 Ba

چکیده
We have measured the ratio of K-shell internal conversion coefficients, αK , for the 127.5-keV E3 transition in 134Cs and the 661.7-keV M4 transition in 137Ba. Previous measurements of these αK values led to a ratio that differed from calculated internal conversion coefficients. Our measured result, 30.01(15), disagrees with, but is a factor of three more precise than, the previous average of all experimental results. Our new result is consistent with calculations.

Internal conversion coefficients in 134 Cs , 137 Ba , and 139 La : A precise test of theory
Recently we measured the ratio ofK-shell internal conversion coefficients, αK , for the 127.5-keV E3 transition in 134Cs and the 661.7-keV M4 transition in 137Ba. We here report a measurement of the 165.9-keV M1 transition in 139La, based on which we convert our earlier ratio measurement into individual αK values for the transitions in 134Cs and 137Ba. These results continue to confirm the Dira...
متن کاملTransfer of 137Cs from Chernobyl debris and nuclear weapons fallout to different Swedish population groups.
Data from measurements on the body burden of (134)Cs, (137)Cs and (40)K in various Swedish populations between 1959 and 2001 has been compiled into a national database. The compilation is a co-operation between the Departments of Radiation Physics in Malmö and Göteborg, the National Radiation Protection Authority (SSI) and the Swedish Defense Research Agency (FOI). In a previous study the effec...
متن کاملMinimal Internal Radiation Exposure in Residents Living South of the Fukushima Daiichi Nuclear Power Plant Disaster
Following the Fukushima nuclear power plant disaster, assessment of internal radiation exposure was indispensable to predict radiation-related health threats to residents of neighboring areas. Although many evaluations of internal radiation in residents living north and west of the crippled Fukushima nuclear power plant are available, there is little information on residents living in areas sou...
متن کاملElectron probe X-ray microanalysis of boar and inobuta testes after the Fukushima accident
We aimed to investigate the effect of chronic radiation exposure associated with the Fukushima Daiichi Nuclear Power Plant (FNPP) accident on the testes of boar and inobuta (a hybrid of Sus scrofa and Sus scrofa domestica). This study examined the contamination levels of radioactive caesium (Cs), especially (134)Cs and (137)Cs, in the testis of both boar and inobuta during 2012, after the Fukus...
متن کاملRadiocaesium activity concentrations in potatoes in Croatia after the Chernobyl accident and dose assessment.
Systematic investigations of (137)Cs and (134)Cs activity concentrations in potatoes (Solanum tuberosum) for the post-Chernobyl period (1986-2005) in the Republic of Croatia are summarized. The correlation between (137)Cs activity concentrations in fallout and potatoes, has been found to be very good, the correlation coefficient being r = 0.88 with P(t) < 0.001 for 18 degrees of freedom. As the...
