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.

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 ...
[90] [91] [92] For instance, over a timeframe of thousands of years, after the most active short half-life radioisotopes decayed, burying U.S. nuclear waste would increase the radioactivity in the top 610 metres (2,000 ft) of rock and soil in the United States (10 million square kilometres, 3.9 million square miles) by ≈ 1 part in 10 million ...
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.
Radioresistance is the level of ionizing radiation that organisms are able to withstand.. Ionizing-radiation-resistant organisms (IRRO) were defined as organisms for which the dose of acute ionizing radiation (IR) required to achieve 90% reduction (D10) is greater than 1,000 gray (Gy) [1]
Natural radiation on a monazite beach near Guarapari, Brazil. [67] (9: Sv/a) 1: mSv/h: NRC definition of a high radiation area in a nuclear power plant, warranting a chain-link fence [68] (17–173: Sv/a) 2–20: mSv/h: Typical dose rate for activated reactor wall in possible future fusion reactors after 100 years.

The Berkeley-hired firm proposed flagging areas for further evaluation if gamma radiation detectors reach 80,000 counts per minute or higher. The typical background reading is 60 counts per minute.
Parts 0 to 199 are the requirements (and reserved for the requirements) prescribed by the United States Nuclear Regulatory Commission (NRC) and binding on all persons and organizations who receive a license from NRC to use nuclear materials or operate nuclear facilities.
