Q

How are radioactive materials being transported labelled and packaged?

A

Consignor must:

  • prepare and close (following instructions)
  • mark and label
  • fill out shipping documentation and sign declaration
  • collect pertinent documentation for package (Special form certificate, package design certificate)
  • provide valid leak test
  • confirm carrier and driver have class 7 certification
  • provide carrier with shipping documentation, competent authority certificates, instructions for loading stowage carriage handling unloading and emergency arrangements, four class 7 placards
  • inform consignee of shipment
  • keep shipping records
17
Q

What are shipping names?

A

Identify the nature and characteristics of the material being shipped.

i.e.
Radioactive Material, Type A Package, Special Form Non-Fissile or Fissile-Excepted

18
Q

What are UN Numbers?

A

For easy identification

i.e.
3332 or 2916

19
Q

What is a Transport Index?

A

Provides control over radiation exposure to transport workers and member of the public + stowage information for carrier.

  • Measure maximum radiation level (mSv/h) 1m from exposure device
  • multiply by 100
  • round to first decimal

i. e.
0. 1

20
Q

What is the Category of Package?

A

Radiation level on surface of package and transport index

i. e.
- I-WHITE (<5uSv/h, <0.05ti)
- II-YELLOW (>5uSv/h to 500uSv/h, 0 to 1ti)
- III-YELLOW (>500uSv/h to 2mSv/h, >1 to 10ti)

21
Q

Category I-WHITE

A

<5uSv/h, <0.05ti

22
Q

Category II-YELLOW

A

> 5uSv/h to 500uSv/h, 0 to 1ti

23
Q

Category III-YELLOW

A

> 500uSv/h to 2mSv/h, >1 to 10ti

24
Q

What are Placards?

A

A vehicle transporting a category III-YELOW must display four class 7 placards on each side of the vehicle (supplied by consignor)
