    Notes: Abstract Results of post-Chernobyl measurement on some foodstuff samples /eggs, meat, fruit, honey, medicinal herbs/ from South-Eastern Roumania are presented. Gamma-ray spectrometry was used; the radioactive concentration values are given in nCi.kg−1 “wet” weight. A strong decrease in concentrations for eggs from 6–7 May /3.0–7.4 nCi for131I, 0.25–0.40 nCi for134Cs, 0.40–0.85 nCi for137Cs per one egg, mainly in the yolk/ to 19–25 May /0.3–1.0 nCi for131I, 0.15–0.25 nCi for134Cs, 0.25–0.40 nCi for137Cs/ was observed. The mean values for lamb meat /joint muscle/ were 500 nCi.kg−1 for131I, 12 nCi.kg−1 for134Cs, 22 nCi.kg−1 for137Cs /18–25 May/. Relatively reduced values were found for fruits, e.g. compared to dairy products1. In May–June 1986, the food consumption in Roumania was strictly limited and controlled by competent authorities.

    Notes: Abstract The two short-lived isomeric states in112In have been reinvestigated by means of the112Cd(d, 2n) and109Ag (α, n) reactions. Measurements of delayed X- andγ-ray, lifetime and TDPAD spectra have been performed. A 6.32(3) keVγ-ray has been identified in the isomeric decay and anM1 multipolarity has been assigned to it on the basis of the measured internal conversion coefficients:α L =196(39) andα tot=231(35). TheE1+M2(δ =+0.24(4)) andE2 multipolarities have been determined for the 263 and 188 keV transitions deexciting the 8−(T 1/2=2.82(2) μs) and 7+ (T 1/2=0.93(2) μs) isomeric states, respectively. A revised isomeric decay scheme is presented.
