The use of the radioactive decay for dating purposes is reviewed. The most important dating methods are discussed. They include radioactive time markers (e.g., Cs), cosmogenic radionuclides (e.g., C, "'Be), decay products of Ra (e.g., Rn, Pb), uranium-thorium-lead chronometers, rubidium-strontium and potassium-argon nuclide pairs, applications of radioactive disequilibrium, dating with fission tracks, and thermoluminescence. Some important results, for instance the age of the Earth and the Moon… 
Radionuclides in groundwaters : contaminants and tracers
As groundwaters serve for drinking-water purposes, radionuclides in groundwater are generally considered as contaminants. Some of the radionuclides contributing to natural radioactivity in
Mass Spectrometry: A Boon to Nuclear Industry
Mass spectrometry is a versatile technique that is used for the determination of elements at the trace and ultratrace level along with the isotope ratios. The accuracy in the quantification of
Radioactive decay data: powerful aids in medical diagnosis and therapy, analytical science and other applications
Abstract Decay data are commonly used to characterise and quantify radioactive material, and provide an important means of understanding the properties and structure of the nucleus. Experimental
An investigation about natural radioactivity, hydrochemistry, and metal pollution in groundwater from Calabrian selected areas, southern Italy
The increasing interest in radioactivity has brought about the need for an assessment of human exposure to radiation. It is, therefore, necessary to examine naturally occurring radioactivity in the
Bayesian analysis of 210 Pb dating
In many studies of environmental change of the past few centuries, 210Pb dating is used to obtain chronologies for sedimentary sequences. One of the most commonly used approaches to estimate the ages
Dating recent peat deposits
Dating recent peat deposits (i.e., past } 300 yrs of peat accumulation) has emerged as an important yet challenging task for estimating rates of organic matter accumulation and atmospheric pollutant

Bayesian Analysis of $$^{210}$$210Pb Dating
In studies of environmental change of the past few centuries, $$^{210}$$210Pb dating is often used to obtain chronologies for sedimentary sequences. One of the most commonly used approaches to


Migration of Fission Products at the Nevada Test Site: Detection with an Isotopic Tracer
Researchers at Los Alamos National Laboratory are studying the migration of fission products away from explosion cavities formed by underground nuclear tests at the Nevada Test Site. In some cases,
The characteristics of radioactive wastes and soils vary over a wide range. Liquid radioactive waste entering the environment will eventually contact the soil or geological matrix; interactions will

Radionuclide mobility and bioavailability in Norwegian and Soviet soils.
The location-specific differences in the distribution of 90Sr and, to a lesser extent, 137Cs arise because of fallout speciation rather than because of local environmental factors.
Diagenesis of chemical associations of 137Cs and other artificial radionuclides in river sediments
Abstract Chemical extraction experiments involving a five‐step leaching sequence similar to that already applied to stable heavy metal isotopes1 indicate that artificial radionuclides in aquatic
