1985 - Helium accumulation in groundwater II: A model for the crustal 4He degassing flux. In most of the United States, gamma spectrometry surveys are currently limited by coarse line spacing (1.610 km) but do show broad regions in the southeastern U.S. An evaluation of sources and the continental flux of crustal 4He in the Great Artesian Basin, Australia. In subsequent years, airborne gamma spectrometry methods were developed, allowing the distinction of signals due to K, Th, and U (International Atomic Energy Agency, 2003 Duval et al., 2005). In general, the variations with the deposition times were by a factor of up to 10. 1985 - Groundwater dating with helium isotopes, I. Soil-to-plant transfers of the radionuclides varied considerably with the times of deposition also. In general, transfer factors show a large degree of variation dependent upon several factors such as soil type, species of plants, and other environmental conditions. Developments in the analysis and management of combustible gases in severe accidents in water cooled reactors following the Fukushima Daiichi accident.

Existing databases are limited to experimental values in a restricted number of soil systems and are largely comprised of temperate environment data. Soil-to-plant factor is one of the important parameters to be used in transfer models for predicting the concentration of radionuclides in crops/plants and for estimating dose impacts to man. The radionuclides released into the environment can give rise to human exposure by the transport through the atmosphere, through aquatic systems, or through soil subcompartments.

The entry of trace contaminants, which are present in the terrestrial environment, into human food chains is controlled in the long term by their uptake by plant roots.
