    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 Various samples from the south-east region of Roumania/greens, fodder, cheese/were analyzed for131I,134Cs and137Cs concentrations in May and July 1986 by γ-ray spectrometry. The concentrations are reported in nCi. kg−1 wet weight. For greens, a considerable decrease was observed for131I/to 3.0–7.0 nCi. kg−1/,134Cs/to 0.5–2.0 nCi.kg−1/ and137Cs /to 1.0–4.0 nCi. kg−1/ from the first half /5–15 May/ till the end of May 1986. For cheese, maximum values were measured between 5 and 15 May /sheep cottage cheese: 500–800 nCi.kg−1 for131I, 25–50 nCi. kg−1 for134Cs, 40–80 nCi. kg−1 for137Cs/; at the beginning of July a considerable decrease /to 5–10 nCi. kg−1 for131I, 1.2–2.0 nCi.kg−1 for134Cs, 2.2–3.0 nCi. kg−1 for137Cs/ was observed. In autumn 1986 a small increase up to 2.0–3.0 nCi. kg−1 for134Cs and 3.4–5.0 nCi. kg−1 for137Cs /in November/ was reported. The population's internal possible contamination was strongly limited by the authorities' severe control of the food-stuff.

    Analysis of protein content in cereals by total-nitrogen proton activation (1985)

    Notes: Abstract The reaction14N(p, n)14O(71 s) is used, with a proton beam of 14 MeV energy and 100 nA intensity. The14O activity is detected by means of its characteristic 2.312 MeV gamma-ray (9.4%), with a NaI(T1) detector. The intensity ratio of gamma-rays to that of the incident particles for the sample, related to a similar ratio in adequate standards determines the nitrogen content in the sample. The measurement is completely automated. If we protect the embryo region during irradiation, the future germination of the analyzed seeds will be normal. Good correlation has been obtained between the results of the present method and those of the chemical Kjeldahl method.
