Incomplete contents:
The atmospheric sampling for tritium as HTO and HT has been continued at the stations at Baring Head Lighthouse, New Zealand, and in Fairbanks, Alaska, and Miami, Florida. In addition, tritium bound to hydrocarbons has also been sampled in Miami. All HT sources are in the Northern Hemisphere; when the global burden of tritium in the form of HTO and HT, was estimated, it was found that the variations between Fairbanks, Alaska, and Miami, Florida, were quite erratic and warranted at least one more northern station. A station was therefore established at Oregon State University's Marine Sciences Center, at Newport, Oregon, on the Pacific Ocean. The station was established on January 15, 1981 and is now functioning without problems. Tabulated results from all four stations are presented. The global inventory of tritium gas was about 1.3 kg of tritium in the mid-70s. It has been steadily decreasing, and the present value, June 1981 is approximately 700 g. This development is attributed to virtual cessation of the reprocessing of nuclear fuel elements and possibly better precautions taken by various nuclear installations handling tritium in gaseous form

The atmospheric sampling for tritium as HTO and HT has been continued at the stations at Baring Head Lighthouse, New Zealand, and in Fairbanks, Alaska, and Miami, Florida. In addition, tritium bound to hydrocarbons has also been sampled in Miami. All HT sources are in the Northern Hemisphere; when the global burden of tritium in the form of HTO and HT, was estimated, it was found that the variations between Fairbanks, Alaska, and Miami, Florida, were quite erratic and warranted at least one more northern station. A station was therefore established at Oregon State University's Marine Sciences Center, at Newport, Oregon, on the Pacific Ocean. The station was established on January 15, 1981 and is now functioning without problems. Tabulated results from all four stations are presented. The global inventory of tritium gas was about 1.3 kg of tritium in the mid-70s. It has been steadily decreasing, and the present value, June 1981 is approximately 700 g. This development is attributed to virtual cessation of the reprocessing of nuclear fuel elements and possibly better precautions taken by various nuclear installations handling tritium in gaseous form
