Radionuclides in the Environment, Radioecology

Invited

Radioactive wastes with elevated natural radionuclides content, like wastes from uranium ore processing, can be deposited relatively close to agricultural areas. It is therefore important to understand the behavior and transport of those radionuclides in the environment. In support to this knowledge, a plant pot experiment was carried out, involving three different types of vegetables (radish,...

Radionuclides in the Environment, Radioecology

Verbal

Radiocesium is a major radionuclide discharged into the environment as a result of the Fukushima Daiichi Nuclear Power Plant accident. Because radiocesium isotopes have relatively long physical half-lives (134Cs: 2.065 years; 137Cs: 30.04 years), they are the most significant long-term radioactive contaminants in the environment. When radiocesium is deposited on solid ground, it remains in the...

Radionuclides in the Environment, Radioecology

Verbal

Various mushroom samples, lichens and pteridophytes are collected nationwide in 2017 and their contents of artificial radionuclides (137Cs, 238Pu, 239,240Pu and 90Sr) are measured to address the growing concerns regarding the radioactive contamination of food products in Korea.
The analysis shows that the activity concentrations of 137Cs range from minimum detectable activity (MDA) to 77...

Radionuclides in the Environment, Radioecology

The Waste Isolation Pilot Plant (WIPP) is a radioactive waste repository operated by the U.S. Department of Energy (DOE) for the permanent disposal of defense transuranic (TRU) and TRU-mixed wastes (wastes that also have hazardous chemical components). Located near Carlsbad, New Mexico, the WIPP facility is the world’s first deep geological disposal facility licensed to accept TRU waste...
