AbstractIn-situ measurement of marine sediment radioactivity does not destroy the stratification of radionuclides in the sediment. We develop a novel seabed sediment radioactive measurement technique using a High Purity Germanium (HPGe) detector. The overall measurement system is designed, and the detector energy calibration is performed. The efficiency is calculated based on Monte Carlo simulations using the MCNP5 code. We compared the efficiency and energy resolution with the NaI(Tl) detection through experiments. NaI(Tl) detection is incapable of identifying the 137Cs artificial nuclides in seabed sediments due to the energy resolution limit. Hence, underwater HPGe detection is utilized due to its high energy resolution, which enables the detection of artificial nuclides 137Cs. The proposed method is of great significance in evaluating marine radioactive pollution.

Analytical Approaches

We present some results on circumstellar envelopes using a Monte Carlo code we are developing. In contrast to analytical approaches, the effects of multiple scattering and the finite sizes of sources and envelope have been incorporated in the models. As an illustration, we fit the light-curve of V444 Cyg as well as the modulation of the linear polarization throughout its orbit.
