The probability of a major accident at nuclear facilities leading to the release of large quantities of radioactivity into the environment is always ensured to be negligibly small. However, even in the event of a major release into the environment, the prompt and effective implementation of countermeasures can reduce the radiological consequences for the public.
The handling of nuclear emergencies requires coordination among different service groups of the nuclear facility. In the event of potential radiological consequences in the public domain, all the authorities at the three levels, i.e., district, state and central, will play a vital role.
This includes the arrangements required to promptly classify an emergency, mitigate the emergency, notify and recommend protective actions off the site consistent with international guidelines, protect those on site, obtain off-site assistance, conduct environmental monitoring of the affected area and assist off-site officials in keeping the public informed.
