Low-level waste
Low-level waste
Low-level waste (LLW) [1] is a type of radioactive waste that is derived from the operations of nuclear power plants, nuclear medicine, and other industries that use radioactive materials.
Etymology
The term "low-level waste" is derived from the fact that this type of waste has a lower level of radioactivity compared to other types of radioactive waste such as high-level waste and intermediate-level waste.
Description
Low-level waste includes items that have become contaminated with radioactive material or have become radioactive through exposure to neutron radiation. This waste typically consists of contaminated protective shoe covers and clothing, wiping rags, mops, filters, reactor water treatment residues, equipment and tools, luminous dials, medical tubes, swabs, injection needles, syringes, and laboratory animal carcasses and tissues. The radioactivity can range from just above background levels found in nature to much higher levels, which can be harmful to humans or the environment.
Disposal
The disposal of low-level waste is straightforward. It is conditioned to reduce its volume and then sealed in containers. The containers are then buried in shallow land burial facilities. To ensure the safety of the environment and the public, the facilities are located away from populated areas and are designed to contain the radioactivity for hundreds of years.

The Template:IPA (International Phonetic Alphabet) is a system of phonetic notation based primarily on the Latin alphabet. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of the sounds of spoken language.
Pronunciation
The pronunciation of the term "IPA" is /aɪ piː eɪ/ in English.
Etymology
The term "IPA" is an acronym for the International Phonetic Alphabet. The International Phonetic Association, founded in 1886, created the IPA to provide a single, universal system for the transcription of spoken language.

- Phonetic notation: A system used to visually represent the sounds of speech. The IPA is one type of phonetic notation.
- Phonetics: The study of the physical sounds of human speech. It is concerned with the physical properties of speech sounds (phonemes), and the processes of their physiological production, auditory reception, and neurophysiological perception.
- Phonology: The study of the way sounds function within a particular language or languages. While phonetics concerns the physical production, acoustic transmission and perception of the sounds of speech, phonology describes the way sounds function within a particular language or languages.
- Transcription (linguistics): The systematic representation of spoken language in written form. The source of the words transcribe and transcription, the term means "to write across" in Latin, and it's the process of converting spoken language into written form. In linguistics, this is often done using the IPA.
