Abstract Objective The relationship between the penetration (P) and air flowrate(Q) of iodine traps, is deduced from the analysis of the relationship between air flowrate and pressure of different type iodine traps. Methods By simulating different technical leak rates, the penetration and pressure of e iodine traps was tested with radioactive methyl iodine method. Results The test result verified the deduced relationship of P2=A/Q + B. Conclusion According to this relationship, a conservative penetration is got at a reduced air flowrate. The penetration of a series iodine traps banks of a nuclear power plant were tested by employing by-pass methods at a reduced air flowrate. It showed that it is a feasible way to test the penetration of iodine traps at special cases.
