Jäännössäteily

Jäännössäteily refers to the residual radiation present in an environment after a radioactive source has been removed or its activity has significantly decreased. This radiation can originate from various sources, including nuclear accidents, the decay of long-lived isotopes, or naturally occurring radioactive materials. The intensity and type of jäännössäteily depend on the specific radioactive isotopes involved and the time elapsed since the initial radioactive event or presence.

Monitoring jäännössäteily is crucial for assessing potential health risks and determining the safety of affected areas for human habitation or activity. Measurement techniques typically involve specialized radiation detectors that can identify and quantify different types of radiation, such as alpha, beta, gamma, and neutron emissions. The presence of jäännössäteily may necessitate decontamination procedures or long-term exclusion zones to protect the public from prolonged exposure. Understanding the nature and behavior of jäännössäteily is fundamental in fields like nuclear safety, environmental science, and emergency response.
