Nuclear power plants pose high risk to public health and safety if radiation is released into surrounding communities and areas. This nuclear emergency level classification response system was firstly developed by the US Nuclear Regulatory Commission to allow effective and urgent responses to ultimately control and minimise any detrimental effects that nuclear chemicals can have.

New findings released from 2021 contamination incident at plant near Richland, WA.
In October 2011, the Nuclear Regulatory Commission (NRC) instructed agency staff to move forward with seven of the 12 safety recommendations put forward by the federal task force in July. The recommendations include "new standards aimed at strengthening operators' ability to deal with a complete loss of power, ensuring plants can withstand ...
When a radiation cloud at high altitude is exposed to rainfall, the radioactive fallout will contaminate the downwind area below. [ 37 ] Agricultural fields and plants will absorb the contaminated material and animals will consume the radioactive material.
The level of health risk is dependent on duration and the type and strength of irradiation. Penetrating radiation such as gamma rays, X-rays, neutrons or beta particles pose the greatest risk from an external source. Low penetrating radiation such as alpha particles have a low external risk due to the shielding effect of the top layers of skin.
High air temperature and radiation from the core limit the time, measured in minutes, people can spend inside containment while the plant is operating at full power. In the event of a worst-case emergency, called a "design basis accident" in NRC regulations, the containment is designed to seal off and contain a meltdown. Redundant systems are ...
The United States Nuclear Regulatory Commission (NRC) is an independent agency of the United States government tasked with protecting public health and safety related to nuclear energy. Established by the Energy Reorganization Act of 1974 , the NRC began operations on January 19, 1975, as one of two successor agencies to the United States ...
Currently the Nuclear Regulatory Commission regulations are found in the Code of Federal Regulations (CFR) under “Energy,” in Chapter I of Title 10. Chapter I is divided into 199 different parts, while only parts 61 and 62 are the principal portions of low-level radioactive waste regulations.
