In-Situ Seawater Gamma Spectrometry with LaBr<sub>3</sub> Detector at a Nuclear Power Plant Outlet

In a nuclear emergency, the application of in situ spectrometers for monitoring environmental radioactivity is significantly important, as information on the type and activity of radionuclides released from the accident can be obtained quickly. However, in emergency environmental radiological monito...
