Radionuclide definition

Radionuclide means a radioactive element or a radioactive isotope.

Radionuclide means a type of atom which spontaneously undergoes radio- active decay.

Radionuclide means a type of atom which spontaneously undergoes radio- active decay.[54 FR 51697, Dec. 15, 1989, as amended at 61FR 68981, Dec. 30, 1996]§ 61.102 Standard.(a) Emissions of radionuclides, in- cluding iodine, to the ambient air from a facility regulated under this subpart shall not exceed those amounts that would cause any member of the public to receive in any year an effective dose equivalent of 10 mrem/yr.(b) Emissions of iodine to the ambi- ent air from a facility regulated under this subpart shall not exceed those amounts that would cause any member of the public to receive in any year an effective dose equivalent of 3 mrem/yr.§ 61.103 Determining compliance.(a) Compliance with the emission standard in this subpart shall be deter- mined through the use of either the EPA computer code COMPLY or the al- ternative requirements of appendix E. Facilities emitting radionuclides not listed in COMPLY or appendix E shall Environmental Protection Agency § 61.104 contact EPA to receive the informa- tion needed to determine dose. The source terms to be used for input into COMPLY shall be determined through the use of the measurement procedures listed in § 61.107 or the emission factors in appendix D or through alternative procedures for which EPA has granted prior approval; or,(b) Facilities may demonstrate com- pliance with the emission standard in this subpart through the use of com- puter models that are equivalent to COMPLY, provided that the model has received prior approval from EPA headquarters. Any facility using a model other than COMPLY must file an annual report. EPA may approve an alternative model in whole or in part and may limit its use to specific cir- cumstances.§ 61.104 Reporting requirements.(a) The owner or operator of a facil- ity subject to this subpart must submit an annual report to the EPA covering the emissions of a calendar year by March 31 of the following year.

Examples of Radionuclide in a sentence

• Radionuclide emission measure- ments in conformance with the re- quirements of paragraph (b) or (c) of this section shall be made at all release points that have a potential to dis- charge radionuclides into the air in quantities that could cause an effective dose equivalent in excess of 1% of the standard.

• Radionuclide concentrations which would cause an effective dose equivalent greater than or equal to 10% of the standard shall be readily detect- able and distinguishable from back- ground.
