Description
Measurement standards and reference materials for radionuclide metrology
Measurement of 222Rn activity in water is important in many fields such as dosimetry, radiation protection, geology and volcanology. Various methods were developed to measure radon-in-water, namely: emanometry, gamma–ray spectrometry (GS), liquid scintillation counting (LSC) and track-etch techniques. Despite the importance of these measurement techniques, their long history and wide scale...

Tritium can be found in several forms, such as gaseous (HT, HTO), liquid (HTO or organic molecules in solution) or organically bound tritium (OBT), which can become incorporated into living organisms (vegetables, animals, humans). The...
Environmental radioactivity monitoring activities are being strengthened owing to concerns about radiation pollution. Therefore, various research laboratories, institutes, and universities are conducting environmental radiation investigations around nuclear power plants (NPPs). However, the reliability of the results continues to trigger controversy in society.
This study was conducted to...
Activated carbon is widely used for short-term (few days) radon sampling with consequent measurement of the adsorbed activity by liquid scintillation counting or gamma-spectrometry. This is a bulk material that can hardly be coupled with external detectors acquiring signal during exposure (e. g. solid state nuclear track detectors, semiconductor or scintillation detectors). The use of...
A new soil reference material (RM) to improve the quality assurance and quality control of the gamma radioactivity measurement in environmental samples was developed by the Korea Research Institute of Standards and Science (KRISS). Depending on the user's request, the type and specific radioactivity of radionuclides to be included in the soil RM can be selected. In this study, the homogenized...

A metal wastes such as pipes, pumps and valves generated in large quantities in the operation of nuclear power plant and during the decommissioning process. In order to dispose of these metal wastes, it is announced that the...
There is always a need for a supply of natural matrix standards for the metrology community and the network of radioanalytical laboratories to validate their radioanalytical methods, control the quality of their measurement process, compare measurements results within and between laboratories/programs, monitor lab performance over an extended period of time. They are also used to support the...
