Module overview

What is the Class 7: Radioactive Material module?

The ADR Class 7 module is specialist training for drivers carrying radioactive material. It begins with ionising radiation—alpha, beta and gamma—radioactive decay, half-life, dose and the short- and long-term effects of exposure. Drivers learn the difference between radiation and contamination, the routes by which radioactive material can produce internal or external dose, and the purpose of dose meters, records, local rules and radiation risk assessments.

Transport controls include containment, time, distance, shielding and hygiene; package types from excepted and industrial packages through Type A, B and C; category I-White, II-Yellow and III-Yellow labels; transport and criticality safety indexes; placards, documents, security, stowage and segregation. Emergency content focuses on avoiding contamination, contacting specialists and emergency services, following the carrier’s arrangements and carrying out decontamination only under appropriate supervision.

Syllabus coverage

What you study in Class 7: Radioactive Material

These themes group the official learning objectives into practical revision areas. Open the topic map below for the exact question-bank structure used by ADR Driver Pro.

Radiation, dose and health effects

Alpha, beta and gamma radiation, decay and half-life, dose pathways and measurement, personal dose records, contamination, background radiation and additional chemical hazards.

Protection and legal controls

Containment, time, distance, shielding and hygiene, together with radiation risk assessment, local rules, security and the responsibilities of consignors, carriers and drivers.

Packages, labels and indexes

Excepted, industrial, Type A, B and C, special-form and fissile packages; I-White, II-Yellow and III-Yellow categories; transport index, criticality safety index and exclusive use.

Loading, stowage and journeys

Package handling, minimum handling, segregation, load and index limits, vehicle marks, pre-journey checks, supervision, parking, breakdowns, customs and delivery.

Radiological emergencies

Avoiding contamination, alerting emergency services, following emergency or contingency arrangements, understanding the NAIR scheme and leaving personal decontamination to specialist supervision.

Qualification context

How this module fits an ADR route

The specialist radioactive route combines Core with Class 7. GOV.UK treats it separately from the general Packages/Tanks and Group A/B paths. Drivers who later add general classes may need the relevant method-of-carriage and class training as well.

Class 7 operations depend on competent radiation-protection arrangements, package documentation and load-specific limits. A revision page cannot replace the radiation risk assessment, local rules or emergency plan used for the real journey.

Revision plan

How to study Class 7: Radioactive Material

1Keep radiation and contamination separate: one is energy exposure, the other is radioactive material where it should not be.
2Build a package-and-label comparison chart that links category, index and stowage implications.
3Apply time, distance, shielding, containment and hygiene to short driver scenarios.
4In emergencies, prioritise isolation, communication, contamination avoidance and specialist control rather than approaching or handling damaged packages.

Common questions

Class 7: Radioactive Material FAQs

What does the ADR Class 7 module cover?

It covers ionising radiation, dose and contamination, radiation protection, package types and labels, transport and criticality safety indexes, security, loading, stowage, journey duties and radiological emergencies.

What is the difference between radiation and contamination?

Radiation is energy emitted from a source. Contamination means radioactive material is present on a person, surface or place where it should not be, creating a risk of spread or internal exposure.

What modules form the specialist radioactive route?

The UK specialist route combines the Core module with Class 7 Radioactive Material. Further modules are needed to add other classes or methods of carriage.
