Radioactive Material Shipping Compliance Guide

A Practical Radioactive Material Shipping Compliance Test

You manage Class 7 shipments and need to know whether your program would withstand a DOT, FAA, carrier, or internal review. This radioactive material shipping compliance test covers classification thresholds, package selection, radiation surveys, labels, shipping papers, employee training, security plans, and internal audits. Apply each test to the isotope, activity, package, employee function, and transport mode involved. A program can comply for a routine highway shipment yet fail when the same material moves by air.

Activity Thresholds and Packaging Determinations: The First Compliance Test

Start with the radionuclide, its form, activity concentration, and total activity in the consignment. Compare both activity measures with the isotope-specific exemption values in 49 CFR 173.436 and IATA Table 10.3.A. A substance falls within Class 7 only when both values exceed the applicable exemptions. For mixed radionuclides, apply the sum-of-fractions calculation rather than evaluating each isotope in isolation.

Next, determine whether the consignment qualifies for an excepted package. The limits in 49 CFR 173.425 and IATA Table 10.3.B are fractions of the applicable A1 value for special form material or A2 value for normal form material. The Conference of Radiation Control Program Directors explains the thresholds that move a shipment out of the exception and into full Class 7 requirements.

If activity exceeds the excepted-package limit but remains at or below A1 or A2, the shipment generally requires an authorized Type A package. Higher activities may require Type B packaging and an active competent-authority certificate. Fissile material requires a separate criticality evaluation. Record the values, calculations, physical form, package determination, and regulatory table edition used so another qualified employee can reproduce the classification.

Physical Packaging Standards, Radiation Surveys, and Contamination Limits

Package compliance depends on more than selecting a box marked “Type A.” Verify that the exact package design is authorized for its contents and keep its test report or other design documentation available. Type A documentation should address water spray, free drop, stacking, and penetration performance. Follow the manufacturer’s closing instructions and document required torque values, seals, absorbent material, shielding, and leak checks.

Survey the completed package with suitable instruments. Check the package surface and the required distance used to calculate its Transport Index. Perform wipe tests where required, and retain the results with the instrument identification and calibration status. Under the excepted-package limits published by Cornell Law School’s Legal Information Institute, the external surface radiation level may not exceed 0.005 mSv/h, or 0.5 mrem/h; applicable non-fixed contamination limits must also be met.

Before dispatch, confirm that the package is undamaged, properly closed, and within its content and activity limits. Air shipments of liquid radioactive material also need packaging capable of meeting the applicable internal pressure-differential requirement. A current survey cannot correct an unauthorized package or an incorrect closure.

Marking, Labeling, and Ground-versus-Air Documentation

Once the package passes its physical checks, compare every mark and label with the classification record. A non-excepted package normally needs its proper shipping name and UN identification number. Packages over 50 kilograms need the required gross-mass marking. Excepted packages still require the applicable UN number even though they do not carry the full Class 7 label set.

Choose White-I, Yellow-II, or Yellow-III from the measured surface radiation level and calculated TI. Complete each label with the radionuclide name or symbol and activity in SI units. Record the TI to one decimal place on Yellow-II and Yellow-III labels, and make sure it agrees with the survey record and shipping document.

For highway movements, check the DOT shipping description, technical Class 7 entries, emergency-response information, and any placarding requirement. For air, use the current ICAO/IATA requirements and carrier variations. The Shipper’s Declaration must be completed in English when required, and the air waybill must contain the required dangerous-goods statement. Packages with a TI from 3.0 through 10.0 are restricted to Cargo Aircraft Only. A package above 10.0 TI requires a competent-authority special arrangement for air carriage.

Training Mandates, Qualification Cycles, and Verifiable Employee Files

At TMGI, we recommend training employees for the work they perform rather than giving everyone the same broad presentation. Classification staff must know how to use isotope activity tables. Packers need package limits and closing instructions. Employees signing air declarations need current air-mode instruction and practice completing the documents they use.

Under the Electronic Code of Federal Regulations, DOT initial training must be completed within 90 days after employment or a change in job function, with recurrent training at least every three years. Employers must retain records covering the preceding three years of training during employment and for 90 days afterward. ICAO/IATA air training follows a two-year recurrent cycle.

A DOT training file should show the employee’s name, latest completion date, description or location of the training materials, trainer’s name and address, and certification that the employee was trained and tested. Map each employee’s duties to general awareness, function-specific, safety, security-awareness, and any required in-depth security training.

Our Class 7 training courses provide function-specific ground training under 49 CFR and air training under ICAO/IATA. TMGI also offers a medical brachytherapy course for short half-life isotopes shipped in Type A packages by air, with Ir-192 featured in the curriculum. TMGI-trained accounts receive regulatory updates, recurrent-training reminders, and telephone support throughout the applicable compliance period. Healthcare and laboratory managers can also review the signs that a facility needs hazmat training.

Security Plans and High-Consequence RAM-QC Thresholds

Some Class 7 operations trigger more than general security-awareness training. A written security plan under 49 CFR 172.800 may be required for high-consequence quantities, including Highway Route Controlled Quantities, applicable Category 1 or Category 2 material, uranium hexafluoride requiring placarding, and NRC RAM-QC radionuclides. Placarded radioactive shipments should prompt a documented review of whether the security-plan requirements apply.

The written plan should identify responsible people, assess site and transportation risks, control unauthorized access, and address en-route security. Routes, handoffs, tracking arrangements, emergency contacts, and communication procedures should reflect the actual operation. Relevant employees must receive the security training needed to carry out the plan.

Failing to maintain a required plan can expose a shipper to potential fines from $3,000 to $7,500. TMGI’s written security plan service can help evaluate the trigger, review risks, and develop or assess the required controls.

Closing Program Gaps Through Proactive Compliance Audits

Do not wait for an official DOT or FAA inspection to test the program. Use structured internal audits to examine representative shipments from classification through carrier tender, including routine isotopes, uncommon consignments, returns, and both ground and air movements where applicable.

Begin with the administrative trail: isotope and activity calculations, package authorizations, shipping papers, declarations, training files, registrations, permits, written procedures, security plans, and emergency-response information. Confirm that the 24-hour emergency number is active while a shipment is in commerce and reaches someone with the required technical knowledge.

Then observe a package being prepared. Compare the work with the written procedure and manufacturer’s closing instructions. Check survey-meter and wipe-counter calibration records, contamination results, TI calculations, label completion, package condition, document review, and final acceptance controls. Assign each finding to an owner and require evidence of corrective action.

TMGI’s proactive hazmat audits review shipping documentation, packaging, marking, labeling, training records, registrations, permits, written procedures, compliance agreements, and security plans. The review is designed to identify gaps before an enforcement inspection or carrier rejection exposes them.
