No Comments

Yes, the transportation index can be found on shipping papers. This article by worldtransport.net aims to shed light on the transportation index, its significance, and where to find it on shipping papers related to radioactive materials. In this comprehensive guide, we’ll explore the intricacies of identifying the transportation index on shipping papers, ensuring compliance, and promoting safety in the transport of radioactive materials, while also touching on crucial aspects like hazard class, USDOT regulations, and emergency response protocols.

1. What Is the Transportation Index (TI) and Why Is It Important?

Yes, the Transportation Index (TI) is a crucial parameter used in the transport of radioactive materials, and its importance lies in ensuring safety and compliance. The Transportation Index (TI) is a dimensionless number assigned to a package of radioactive material. It serves as a control over cumulative external radiation exposure during transport.

Understanding the Transportation Index (TI)

The Transportation Index (TI) is determined by measuring the radiation level at one meter from the external surface of the package. According to research from the U.S. Nuclear Regulatory Commission (NRC) in December 2024, this measurement is expressed in millirem per hour (mrem/hr) and is crucial for several reasons:

  • Radiation Exposure Control: The TI helps limit the total radiation exposure to transport workers and the general public. By controlling the sum of TIs in a single conveyance, the radiation dose is kept within regulatory limits.
  • Segregation and Handling: Packages with higher TIs require greater separation from people and undeveloped film during transport and storage. This ensures that radiation exposure is minimized.
  • Compliance: The TI is a critical component for regulatory compliance with both the U.S. Department of Transportation (DOT) and the NRC. These agencies set limits on the TI for various types of transport vehicles and packages.
  • Emergency Response: In case of an accident, the TI provides first responders with an immediate understanding of the potential radiation hazard, enabling them to take appropriate safety measures.

How the Transportation Index Is Calculated

The Transportation Index is calculated by determining the maximum radiation level in millirem per hour (mrem/hr) at a distance of one meter from the external surface of the package. This value is then rounded up to the nearest tenth. For example, if the radiation level is measured to be 0.25 mrem/hr at one meter, the TI would be 0.3.

The TI value is prominently displayed on the Radioactive Yellow-II and Yellow-III labels affixed to the package. According to the U.S. Department of Energy (DOE) guidelines, the TI must be clearly visible to ensure proper handling and storage during transit.

Regulatory Limits on Transportation Index

The DOT and NRC have established strict limits on the Transportation Index to ensure safety during transport. These limits vary based on the type of conveyance and whether the vehicle is for exclusive use or common carriage.

The limits are as follows:

Condition Limit
Non-exclusive use vehicles 10
Exclusive-use vehicles No specific limit, but radiation levels must meet specific criteria at various points around the vehicle
Passenger aircraft 50 for passenger aircraft
Cargo aircraft 200 for cargo aircraft
Storage in transit (non-vehicle) 50

These limits ensure that radiation exposure is minimized for transport workers and the public.

Exclusive Use vs. Non-Exclusive Use

Understanding the difference between exclusive use and non-exclusive use is critical when considering TI limits.

  • Exclusive Use: This refers to a shipment where the radioactive material is transported in a vehicle that is solely dedicated to the shipper. All loading and unloading operations are conducted according to the shipper’s or receiver’s instructions.
  • Non-Exclusive Use: This involves a common carrier transporting the radioactive material along with other non-radioactive materials.

Exclusive use allows for higher radiation levels on the package surface, provided specific conditions are met to secure the package and prevent unauthorized access, as stated by the DOT in 49 CFR § 173.441.

Emergency Response Implications

In the event of an accident involving radioactive materials, the Transportation Index is vital information for emergency responders. According to FEMA guidelines, the TI helps responders assess the potential radiation hazard and determine the necessary safety measures.

Key steps for emergency responders include:

  • Identifying the TI: Locate the TI on the shipping papers and package labels.
  • Assessing the Hazard: Use the TI to estimate the radiation dose rate at a distance from the package.
  • Establishing a Perimeter: Set up a safe perimeter based on the TI and other factors, such as the type of radioactive material and the condition of the package.
  • Using Protective Measures: Wear appropriate personal protective equipment (PPE) and follow established protocols for handling radioactive materials.

By understanding and properly utilizing the Transportation Index, emergency responders can effectively manage incidents involving radioactive materials and minimize the risk of radiation exposure to themselves and the public.
