Fig. 3. Relationship between dead layer thickness and simulation efficiency of ²⁴¹Am point source. Black spot data comes from simulation efficiency, horizontal line comes from experimental data, and vertical line determines thickness of dead layer through experimental and simulation linear function calculation
