What maximum radiation level is permissible at 10 cm from an unpackaged gauge for it to be classified as an Excepted Package?

The requirement for classifying a gauge as an Excepted Package hinges on the permissible radiation level at a specific distance from the package. For an unpackaged gauge, the maximum allowable radiation dose at a distance of 10 cm is set at 0.1 mSv/hour. This threshold is established to ensure that the potential exposure to individuals handling or being near the gauge remains within safe limits, minimizing health risks associated with radiation.

In regulatory terms, an Excepted Package is one that is considered to pose a minimal risk during transportation, and the radiation level is a critical parameter that helps determine this classification. The specified limit of 0.1 mSv/hour indicates a balance between usability for certain applications and the need for safety in environments where radiological materials are present.

Understanding this standard is crucial for professionals working with radiation, as it facilitates compliance with safety regulations and helps protect both operators and the public from unnecessary exposure to radiation.
