During normal operation, authorised discharges of radionuclides can occur in very low quantities, controlled by radiological limits, environmental monitoring, and reporting. This does not mean that a plant 'irradiates' the environment continuously at dangerous levels. Institutional sources distinguish between authorised emissions, effective dose to the public, and natural background levels.
