Abstract
Radioactive cesium concentration in soil was measured at 27 sections with 5 points per section, and surface dose of ground was measured at 10 sections with 13 points per section at a farm in Fukushima to assess local variation of soil contamination with radioactive cesium. As for the cesium in soil, averages of the coefficient of variance (CV) and the maximum/minimum ratio in each section were 49% and 4.9, respectively. As for the surface dose, average of its CV in each section was 20% and the maximum/minimum ratio reached a maximum of 3.0. These findings suggest that exact evaluation of soil contamination with cesium is difficult. Small changes or differences in soil contamination may not be detected in studies of the environmental radioactivity.
期刊介绍：
The Japanese Journal of Veterinary Research (JJVR) quarterly publishes peer-reviewed articles on all aspects of veterinary science. JJVR was originally published as a “University Journal” of veterinary science at Hokkaido University from more than 60 years ago. Currently, JJVR, is Japan’s leading scientific veterinary journal, and provides valuable information for the development of veterinary science by welcoming contributions from researchers worldwide.
JJVR offers online submission for Regular Papers, Short Communications, and Review Articles that are unpublished and not being considered for publication elsewhere. Research areas include:
Anatomy, Physiology, Biochemistry, Pharmacology, Microbiology, Infectious diseases, Parasitology, Laboratory Animal Science and Medicine, Internal Medicine, Surgery, Pathology, Theriogenology, Molecular Medicine, Public Health, Radiation Biology, Toxicology, Wildlife Biology and Medicine, Veterinary Hygiene, The other fields related to veterinary science.
