Abstract: This paper simulates the detection efficiency of the detector crystal of FD3013 digital gamma ray radiation instrument to ¹³⁷Cs gamma source using Monte Carlo simulation tool kit Geant 4.The protection lead tin's protective effect of TH-PPL CT teaching instrument is also studied.To simulate the trunk dosage,a simple trunk model is established,the simulation results show that the protective effect is acceptable.
