Transportation of radioactive material is regulated by the Nuclear Regulatory Commission and Department of Transport. Material is defined as radioactive when the specific activity exceeds 70 Bq/g. The activity in tumor and sentinel node, directly following the surgical removal is usually less than 10 MBq and therefore can be considered to be a ''limited quantity'' . Transportation in a strong and tight package will be sufficient in most cases. The package in which the material is transported needs external labeling to indicate the type and amount of radioactivity. Provided that the radiation levels at the surface of the package are below 5 |j,Sv/h, a marking of ''radioactive'' on the exterior of the package is sufficient.
