Transport Index - TI [Energy] Law and Legal Definition
According to 10 CFR 71.4 [Title 10 – Energy; Chapter I -- Nuclear Regulatory Commission; Part 71 -- Packaging and Transportation of Radioactive Material; Subpart A -- General Provisions], the term Transport index (TI) means “the dimensionless number (rounded up to the next tenth) placed on the label of a package, to designate the degree of control to be exercised by the carrier during transportation. The transport index is the number determined by multiplying the maximum radiation level in millisievert (mSv) per hour at 1 meter (3.3 ft) from the external surface of the package by 100 (equivalent to the maximum radiation level in millirem per hour at 1 meter (3.3 ft)).”
