A gaseous sampling system was developed to differentially collect all major volatile forms of tritium and carbon-14 according to chemical class. These chemical forms include: tritiated forms of water, hydrogen and organics; as well as 14C-containing carbon monoxide, carbon dioxide and organics. Sampling campaigns involving the use of this differential 3H and 14C collection system have been successfully conducted at a high level liquid waste solidification plant, at a spent fuel storage facility and in the vicinity of power reactors.

This paper describes the current status of research on an improved tritium measurement system at the Oak Ridge National Laboratory (ORNL) for the US Navy. Present tritium-in-air monitoring systems installed by the Navy can reliably measure to less than 10 [mu]Ci/m3, but medical and safety issues are pushing measurement needs to below 1 [mu]Ci/m3, which is equivalent to 1--10 nCi/ml in liquid samples, using calcium metal converter. A significant effort has been expended over the past 10 years by the Navy RADIAC Development Program at ORNL on various schemes to improve the detection of tritium in both air and liquid at near ambient levels. One such scheme includes a liquid flow-through system based on an NE102 sponge scintillator with dual photomultiplier tubes for the tube noise rejection. (This document also contains copies of the slides used for presentation of this paper to the IEEE 1991 Nuclear Science Symposium). 4 refs., 17 figs.

Tritium and radiocarbon are pure beta emitters. Tritium has an average energy of 5.7 keV and endpoint energy of 18.6 keV [1]. Radiocarbon has an average energy of 49.5 keV and endpoint energy of 156 keV. The half-life of tritium and radiocarbon is 12.3 years and 5730 years, respectively. Hydrogen has three isotopes, namely hydrogen (1H), deuterium (2H), and tritium (3H). Among the three isotopes, tritium alone is a radioactive isotope. The natural abundance of hydrogen, deuterium, and tritium are 99.985%, 0.015%, and 1x10-18%. Carbon is also having three isotopes 12C, 13C, and 14C. The isotopes 12C and 13C are stable, whereas 14C is radioactive. The natural abundance of 12C, 13C and 14C are approximately 98.89%%, 1.11% and 1.2 x 10-10% respectively. Tritium is continuously produced in the atmosphere with cosmic-ray induced neutron activation of atmospheric gases. The reaction occurs with fast neutrons. The threshold neutron energy for the 14N (1n, 3H) 12C is 4 MeV [1].

This publication contains information on the dosimetry and monitoring of tritium, the use of protective clothing for work with tritium, safe practices in tritium handling laboratories and details of tritium compatible materials. The information has been compiled from experience in the various applications of tritium and should represent valuable source material to all users of tritium, including those involved in fusion R&D.
