Radiation pollution is a problem faced by many countries around the world. This can be caused by various factors such as accidents at nuclear power plants, nuclear weapons testing and other sources of radiation. Generally, radiation contamination leads to negative consequences for human health and the environment, so it must be controlled and eliminated.
One way to eliminate radiation contamination is decontamination. Decontamination is the process of removing radioactive substances from the surface of objects or materials. Typically, various methods are used for decontamination, such as mechanical cleaning, chemical treatment and the use of special solutions.
However, not all radioactive substances are removed during decontamination. Some of them may remain on the surface of an object or material, even after decontamination procedures. These radioactive contaminants that are not removed by decontamination are called “residual radioactive contamination” (RRC).
RRR can be removed using various methods, such as mechanical cleaning using special tools and equipment, chemical treatment using special solutions and ultrasonic treatment. However, these methods can be expensive and require specialized equipment and knowledge.
In addition, RRR can be spontaneously removed from the surface of an object or material. This occurs when radioactive particles break off from a surface and enter the environment, where they can be removed by wind, rain, snow or other natural phenomena.
Thus, RRR is a serious problem in the field of radiation safety. To eliminate it, it is necessary to use various methods, including decontamination and spontaneous removal. It is also important to conduct regular checks for the presence of RRD and take corrective action if found.
Radioactive contamination being removed from the surface
Radioactive contamination can come from various sources and forms. One of the most common sources is nuclear testing and radioactive waste that is produced by the use of nuclear power plants, nuclear bombs and other nuclear technology. In the environment, radioactive isotopes can be
