Trends in the human sex odds at birth in Europe and the Chernobyl Nuclear Power Plant accident

Title: Trends in the human sex odds at birth in Europe and the Chernobyl Nuclear Power Plant accident

Author: Hagen Scherb, Kristina Voigt

Reference: Reproductive Toxicology, Volume 23, Issue 4, June 2007, Pages 593–599

DOI: http://dx.doi.org/10.1016/j.reprotox.2007.03.008

Keywords: Analytical ecological study; Exposure–response relation; Low-level ionizing radiation; Male proportion; Radiation epidemiology; Radiation-induced genetic effects; Sex ratio; Spatial–temporal logistic regression

Abstract: To investigate trends in the sex odds before and after the Chernobyl accident, gender-specific annual birth statistics were obtained from the Czech Republic, Denmark, Finland, Germany, Hungary, Norway, Poland, and Sweden between 1982 and 1992. For parts of Germany, annual birth statistics and fallout measurements after Chernobyl are available at the district level. Trend models allowing for discontinuities of the male birth proportions are suggested. Superimposed on a downward trend in male proportions there was a jump in 1987 with a sex odds ratio of 1.0047 (95%-confidence interval: 1.0013–1.0081, p = 0.0061). A positive association of the male proportion in Germany between 1986 and 1991 with radioactive exposure at the district level is reflected by a sex odds ratio of 1.0145 per mSv/a (1.0021–1.0271, p = 0.0218). These findings suggest a possible long-term chronic influence of the Chernobyl Nuclear Power Plant accident on the human sex odds at birth in several European countries.

A Study on the Prefectural Distribution of Radioactive Cesium Concentrations in Dried Lentinula edodes (Shiitake) Produced in Japan

Title: A Study on the Prefectural Distribution of Radioactive Cesium Concentrations in Dried Lentinula edodes (Shiitake) Produced in Japan

Author: Masami SHIMIZU, Ikuro ANZAI, Masahiro FUKUSHI, Yoshiyuki NYUUI

Reference: RADIOISOTOPES, Vol. 46 (1997) No. 5 P 272-280

DOI: http://dx.doi.org/10.3769/radioisotopes.46.272

Keywords: radioactive cesium, dried Lentinula edodes (Shiitake), regional distribution, Japanese product

Abstract: After the Chernobyl nuclear power plant accident, relatively high radioactive cesium levels were detected in various mushrooms produced in many countries. Mushrooms have a high transfer factor, showing a relatively high uptake of cesium from wood and soil in which they grow. In the present investigation, we analyzed radioactive cesium concentrations contained in the dried Lentinula edodes (Shiitake) produced in various prefectures all over Japan, and examined the effectiveness of this mushroom as an indicator of radioactive contamination of environment due to nuclear explosion tests and Chernobyl power plant accident.

Dynamics of the population (population transition) of the Kaluga region before and after the accident at the Chernobyl nuclear power plant

Author: Pisarenko, Taras Sergeyevich

Reference: thesis 03.00.16

Keywords: Environment

Abstract: The purpose of the present work is to study the dynamics of mortality in the Kaluga region for the period 1950 to 2002, of people living in conditions of chronic exposure to artificial radionuclides.

Research objectives: to characterize the radioecological situation in the Kaluga region before and after the accident at the Chernobyl NPP, to identify the dynamics of mortality of different age-sex groups in the rural and urban population before and after the accident, to determine the significance of various classes of causes of death of people in the total structure of mortality in the human population, to compare the dynamics of mortality by cause of death in the human population with the dynamics of radioactive contamination of the atmosphere…
