Estimation method for planned effluent emission dose suitable for nuclear facility site selection

The invention relates to an effluent planned emission dose estimation method suitable for nuclear facility site selection, and belongs to the technical field of nuclear facility environmental impact evaluation, and the method comprises the following steps: S1, determining the annual total emission amount of radionuclides emitted to a given environmental medium by a facility or an activity plan according to the existing information; s2, calculating the average activity concentration of radionuclides in the given environmental medium at a given distance from the emission point where representative personnel are located; s3, calculating the annual dose of representative personnel caused by the average activity concentration of radionuclides in the discharged environmental medium; s4, if the annual dose of the person is judged to be lt; if the dose constraint value meets the screening condition, ending the evaluation; otherwise, if the screening condition is not met, performing higher-level evaluation, or modifyi
