Assessment of the radiological impact of coal utilization. I. Preliminary studies on Western coal. [Western USA; radionuclide impurities]

“…Because the wind was from the northwest 50% of the sampling time, it would-be expected that if the stack emissions were significant the maximum radionuclide concentration would be observed at the south- (1) radon-222 is in secular equilibrium with uranium-234 in coal, and .. McBride et al [36] have suggested that, ..…”

Ethical Perspective on Turkish Environmental Impact Assessment for Nuclear Energy

“…The EIA report, produced by a private Turkish company so called Dokay [1], and approved by Turkish government on December 2014, which includes the amount of annual radioactive release shown in section V. indicates that annual air-born releases from a 1,000 MWe PWR is about 13.935 Curie, 1,100 curies of which is tritium, mostly in gas form [5].…”

Potential health and environmental effects of trace elements and radionuclides from increased coal utilization.

“…and other animals through inhalation and plants through fumigation while those entering the aquatic and terrestrial environments reach plants and animals through root uptake and ingestion. Trace elements and radionuclides in U.S. coals have been widely studied (4,7,8). Concentrations of trace elements in coal are sometimes difficult to determine accurately and tend to vary considerably among different coal types (Table 1).…”

“…Numerous reports have been prepared in recent years concerning these effects relative to our current pattern of coal utilization of approximately 650 million tons per year. Most studies have dealt with specific parameters of coal utilization such as health effects of coal combustion (1), toxicity of coal-derived trace elements (2), effects of coal-derived trace elements on water quality (3), and effects of coal-derived radionuclides (4). Recently several reports have appeared addressing an integrated assessment of coal utilization (5-8) and these reports have been utilized extensively in developing the following materials.…”
