In this paper, a well typed phoswich detector consisting of CsI and plastic scintillators has been designed. This detector can measure Beta and Gamma rays simultaneously. Beta signals, Gamma signals and combination signals can be distinguished using Pulse Shape Analysis. ¹³⁷Cs, ²⁴¹Am and ¹³³Ba radioactive sources have been used to test this detector. It clearly shows that this phosiwch detector can be used for low level radioactivity measurement with Beta-Gamma coincidence method.
