Radiographic sources are classified under which type of packing?

Radiographic sources are classified as "special form" packing. This classification is used because these sources are designed to be stable and secure, minimizing the risk of accidental release of radioactive material. Special form packaging ensures that the radioactive contents can withstand specified tests, such as impact and puncture tests, without losing their integrity.

This is particularly crucial for radiographic sources, which are often used in environments where they may be subjected to rough handling or adverse conditions. The designation as special form signifies that they are contained in a protective casing that safeguards against leakage or dispersal of radioactive material, thus protecting both the handlers and the environment from potential contamination.

In contrast, general form packaging does not imply the same level of security and stability, making it unsuitable for the transportation and use of radiographic sources. Liquid form refers to packaging for radioactive liquids, and plastic form does not pertain to the types of packaging used for radiographic sources, which must meet stringent regulatory requirements regarding safety and containment.
