Establishment of a low-dose ionizing radiation (LDIR) environment simulator.
Escherichiacoli DH5α was selected as a bacterial representative for investigation.
Precise LDIR intensity for E. coli DH5α was calculated by FEA and plasma theory.
Development of system dynamics model of LDIR influence on E. coli DH5α population.
Mechanism of bacterial boom in LDIR environment was elucidated by computer simulation.
