What is a ‘sealed source’ in the context of nuclear gauges?

A ‘sealed source’ refers to a radioactive material that is securely encased in a protective structure designed to prevent the release of radioactive substances into the environment. This encapsulation minimizes the risk of exposure to both the user and the general public, making it crucial for safety in the context of nuclear gauges. The construction of the sealed source includes barriers made from materials capable of containing radiation, ensuring the radioactive material remains contained even if the source is subjected to physical stress or damage.

The effectiveness of sealed sources is essential in applications such as industrial measuring devices and radiography. By being designed to withstand various conditions, they contribute significantly to the safety protocols surrounding the use of radioactive materials.
