Understanding the Transport Index - TI [Energy] and Its Importance

Definition & Meaning

The transport index (TI) is a dimensionless number that indicates the level of control needed by a carrier when transporting radioactive materials. This number is displayed on the package label and is calculated by measuring the maximum radiation level in millisieverts (mSv) per hour at a distance of one meter from the package's surface. The TI is determined by multiplying this radiation level by 100, which also reflects the maximum radiation level in millirems per hour at the same distance.

Real-world examples

Here are a couple of examples of abatement:

For instance, if a package emits a maximum radiation level of 0.05 mSv per hour at one meter, the transport index would be calculated as follows:

  • 0.05 mSv/hour — 100 = 5 (rounded to the nearest tenth).

This means the TI for this package would be 5, indicating that the carrier must take specific precautions during transport.

State-by-state differences

Examples of state differences (not exhaustive):

State Transport Index Regulations
California Strict regulations on transport of radioactive materials, with specific TI labeling requirements.
Texas Follows federal guidelines but has additional state-specific safety protocols for transport.
Florida Requires compliance with both federal and state regulations, with emphasis on public safety.

This is not a complete list. State laws vary, and users should consult local rules for specific guidance.

What to do if this term applies to you

If you are involved in the transport of radioactive materials, ensure that you understand the transport index assigned to your packages. Follow all relevant safety guidelines and regulations. You can utilize US Legal Forms' templates to help manage the necessary documentation and compliance requirements. If your situation is complex, consider seeking professional legal advice to ensure full compliance with applicable laws.
