Although other radionuclides have been found in Japan, these two pose the greatest long-term threat to human health through ingestion and external exposure.
By that time, according to officials, the three had moved into a part of the building designated as a "safe haven," with fortified doors and no external exposure.
External exposure was monitored using thermoluminescence dosimeters (TLDs).
Does she care more about internal politics or external exposure?
The main natural contributors to external exposure from gamma rays are 226Ra, 232Th, and 4K.
Most of this research has focused on the effect of external exposure to elements on nematode.
Cancer mortality risk were estimated due to external exposure to 40K in soil.
External exposure is determined by chemical analysis of the chemicals in food, water or air.
External exposure was determined by personal air monitoring of the 16 EPA-PAH.
The external exposure to staff of the treatment plant is estimated.
The code can handle exposure pathways that include: external exposure from finite or infinite atmospheric plumes; inhalation; external exposure from contaminated soil, sediments, and water; external exposure from special geometries; and internal exposures from consumption of terrestrial foods, aquatic foods, drinking water, animal products, and inadvertent intake of soil.
