Section 340.940 Labeling
Containers and Radiation Machines
a) The licensee shall ensure that each container of licensed
material bears a durable, clearly visible label bearing the radiation symbol
and the words "CAUTION, RADIOACTIVE MATERIAL" or "DANGER,
RADIOACTIVE MATERIAL". The label shall also provide information (such as
the radionuclides present, an estimate of the quantity of radioactivity, the
date for which the activity is estimated, radiation levels, kinds of materials
and mass enrichment) to permit individuals handling or using the containers, or
working in the vicinity of the containers, to take precautions to avoid or
minimize exposures.
b) Each licensee shall, prior to removal or disposal of empty
uncontaminated containers to unrestricted areas, remove or deface the
radioactive material label or otherwise clearly indicate that the container no
longer contains radioactive materials.
c) Each registrant shall ensure that each radiation machine is
labeled in a manner that cautions individuals that radiation is produced when
it is energized.
