Measurments of Tritium Concentrations in Environmental Water Samples in the Hachinohe Area

We have measured tritium concentrations in the environmental water samples using a liquid scintillation counting system since 1987. In this report we describe the technical procedures to obtain tritium concentrations and show the various tritium levels in water samples revealed in the Hachinohe area. The input data capacity of latitude and longitude values are limited only to degrees. The exact values are as follows: Min. Latitude: 40deg. 20min. N Max. Latitude: 40deg. 40min. N Min. Longitude: 140deg. 50min. E Max. Longitude: 141deg. 41min. E
