Grasping the nuclide species and amount of radioactive materials in environmental samples is important as basic data for evaluating the influence of radioactive materials released into the environment.

The Fukushima Environmental Safety Center is aiming at the development of simple and rapid analysis methods for organically bound tritium (OBT: Organically Bound Tritium) and radioactive strontium (90Sr), which takes time to acquire data. Also we are advancing the efforts towards the application of the method to environmental samples.
