The Compliance Guide for Portable Nuclear Gauges ORS G12A is a practical guide to implement radiation safety measures under the Code of Practice for Sealed Radioactive Material in the civil engineering and horticulture industries where portable nuclear gauges are used.

The Guide gives practical guidance on some of the most common regulatory compliance issues that arise in dealing with portable nuclear gauges, also known as nuclear density meters, and associated ancillary services.

Following the Guide is not a radiation safety requirement. However, in most cases, following the Guide will be equivalent to demonstrating compliance with radiation safety requirements. The Guide makes references to the relevant radiation safety requirements as appropriate.

The Guide is not intended to replace advice from a qualified expert.
