aseous Effluents - Summation of All Discharges,” contains a summation of all gaseous effluent discharges from all release points and all modes of release. The data are subdivided by quarter and year for each radionuclide category: (a) fission and activation gases, (b) iodines/halogens, (c) particulates, (d) tritium, and (e) gross alpha. Table A-1A, “Gaseous Effluents—Ground-Level Release—Batch Mode,” contains a summation of gaseous effluent releases from ground-level release points in the batch mode of release for five radionuclide categories: fission and activation gases, iodines/halogens, particulates, tritium, and gross alpha. Licensees should report the following: 1. curies of each radionuclide discharged by quarter and year, and 2. total curies discharged in each radionuclide category (fission and activation gases, iodines/halogens, particulates, tritium, and gross alpha) by quarter and year. Some licensees may have surveillance requirements allowing the non-noble gas radionuclides (e.g., iodines and tritium) for some types of batch releases (e.g., containment purge) to be reported with continuous release results. In these instances, the table entries for the affected radionuclides for batch releases should include an appropriate designation (e.g., “*”) and an accompanying footnote describing this situation. Table A-1B, “Gaseous Effluents - Ground-Level Release - Continuous Mode,” contains a summation of gaseous effluent releases from ground-level release points in the continuous mode of release for five radionuclide categories: fission and activation gases, iodines/halogens, particulates, tritium, and gross alpha. Licensees should report the following: Rev. 2 of RG 1.21, Page 35 1. curies of each radionuclide discharged by quarter and year, and 2. total curies discharged in each radionuclide category by quarter and year. Table A-1C, “Gaseous Effluents.-.Elevated Release.-.Batch Mode,” contains a summation of gaseous effluent releases from
