Nuclear techniques can be used to identify the source of environmental contamination, such as in the case of nuclear accidents or incidents. This information can be used to better understand the impact of the contamination and to develop effective remediation strategies. One example is in the use of nuclear radiation to measure the thickness of materials in industrial settings. Nuclear techniques can also be used to monitor air and water quality, as well as to detect and measure pollutants. It is important to ensure that these technologies are used safely and responsibly to minimize the risks associated with radiation exposure.
