Background Continued Radiation monitors can be used to check incoming scrap for radioactive material; however, they cannot always detect radioactive material that may be carried in a load or otherwise shielded from the radiation monitor. Keep in mind that items that are not normally radioactive can set off radiation monitors if radioactive contamination is present in or on the surface of the items. Note that some radioactive material is permitted to be disposed of without special requirements. If you suspect radioactivity in an item, contact your state radiation control agency.
Typical Labeling The following are examples of terms normally used in association with the radiation warning symbol to indicate the type of radioactive material and its quantity.

Background
Items that contain radioactive material come in different forms, shapes, and sizes.
These items can turn up in scrap material.
You should be alert to the presence of items that may contain radioactive material. Be familiar with the typical markings such as the three-bladed radiation warning symbol, and the terms used to describe the radioactive materials most used in these devices. Remember that some radioactive material may not be properly marked with the radiation warning symbol, or the radiation warning symbol may be covered by dirt, oil, or rust.
Since 1983, radioactive material has been detected in scrap metal numerous times. In some cases, the radioactive material was contained in shielded devices that found its way into scrap handling facilities and was processed in normal scrap. This resulted in contamination of the facilities, radioactive products in the flue dust, and potential radiation exposure to the works. The contaminated products could have been hazardous to members of the public as well.
