WebbIt has a short half-life of 7.1 sec and decays via beta decay. This decay is accompanied by the emission of very energetic gamma rays (6 MeV), which can readily penetrate the wall of the high-pressure piping and can therefore be easily measured by ion chambers located on the hot leg piping of each coolant loop.
WebbSkyshine radiation, because of its properties, was also a challenge for Serpent's response matrix based importance solver which is why the weight-window generator, based on estimating adjoint function by MC-simulation, was used. This approach worked well for the skyshine problem. For other cases where scattering in low density Webb5 apr. 2024 · Simulation of PEP-II Accelerator Backgrounds Using TURTLE.
