Abstract
|
|
|
In order to measure the Radionuclides and Concentration, the directly grinded land samples (river soil, pine leaves and
mugwort) among the environment samples around the nuclear power plant were filled in a 450 mL Marinelli beaker and
weighed to obtain the dry mass ratio of the samples. Then the background and land samples were measured for 80,000 sec.
The analysis of the collected land samples showed that most of them contained less radiation nuclide than the detection
minimum limit in the ‘Ministry of Education, Science and Technology Public Notice No. 2010-32.’In others, the natural
radionuclides 40K were detected.
Of the products of nuclear reaction discharged by a nuclear reaction, 134Cs and 137Cs are more easily detected, and their
discharge sources can be traced using the relative ratio. Although the radioactive concentration in the vicinity of Kori Nuclear Power Plant, which is more than 1,100km away from Fukushima, the Japanese nuclear accident site, continuous monitoring is needed as the radionuclides can still be accumulated in the soil or animals and plants.
