Abstract: Aiming to evaluate the necessity of carrying out the 2nd nationwide environmental radiation level survey, the environmental monitoring surveys carried out ever since the 1st nationwide natural radiation level survey were investigated, among which monitoring objects or environmental medias, monitoring items and the coverage of monitoring sites of each survey were analyzed. Several shortages were found, for example, data for air sample and biological sample are insufficient, activity concentration of artificial radionuclides needs to be further investigated, coverage of marine monitoring requires improvement, radon concentration survey wasn't paid adequate attention, terrestrial aquatic radioactivity survey needs to be further strengthened, etc. In summary, in the nearest future, establishment of environmental survey database, correspondent surveys for compensating the previous shortages should be the focused. Therefore, the 2nd nationwide survey was not suggested to be carried out currently.
