Flammable
Most explosives, flammable
liquids and flammable gasses
are classified as hazardous
material
HAZMAT Also Includes:
Poisons.
Oxidizers.
Acids.
Infectious waste.
And The Reason
You Are Here:
Radioactive Material (RAM) is also
HAZMAT.
What Does the 7 Mean?

HAZMAT is divided into nine hazard classes
(some contain sub classes like 5.1).
 Radioactive material is number 7, referred to as
“class 7 (radioactive).”
Why Does RAM = HAZMAT?

Radioactive material is listed as hazmat in 49
CFR 172.101.
 49 CFR 173.403 – states, “radioactive material
is any material having a specific activity greater
than 70 Bq/g (0.002 Ci/g).”

The DOT and NRC

DOT is responsible for HM shipments.
 NRC says DOT rules apply even if shipment is
not in commerce.
 NRC has written shipping Regs to comply with
DOT Regs for type B shipments.
The DOT and ICAO

HM may be transported per international civil
aviation organization technical instructions
(ICAO TI) before or after transport by aircraft
if packaged, marked, classified, described and
certified on shipping papers as required by
ICAO TI.
DOT and International Agencies

Follow IAEA safety series no. 6. DOT
basically adapts IAEA regulations but is only
in full compliance with 1985 edition.
DOT and State / Local Auth.

States may make their own rules
provided:
It is possible to comply with both the state
rules and DOT rules.
The rules are not an obstacle to
accomplishment and execution of the
regulations.
DOT and Tunnels

DOT has no regulations specific to tunnels.
 States are responsible for tunnel regulations.
 Some states limit access to tunnels when carrying
RAM.
 Restrictions usually pertain to activity, TI, size
and weight.
Summary

Shipping has proven to be relatively safe.
 A single shipment may fall under several
different agencies regulations.
 Radioactive material is HM per 49 CFR.
 HM employees require specific training.
Summary

HM training must be tested, documented and
certified.
 NRC can & will inspect shipping of radioactive
material.
Transportation of
Radioactive Material
Objectives

Identify the seven steps for shipping
radioactive material:
– Classification.
– Packaging.
– Marking.
– Labeling.
– Shipping papers.
– Placarding.
– Carriage.
Objectives

Understand the procedure for completing steps
one and two of the seven steps.
Step One - Classification

Is the material regulated? (173.403).
– Specific activity >0.002 Ci/g.
– All RAM is listed on table 173.435.

Is the shipment outside of a restricted access
installation?
 If YES then 49 CFR applies.
Containment

Containment type:
– Is the item special form or normal form?

Look at 173.403.
Special Form (173.403)

Class 7 material which:
 Is a single solid piece or contained in a sealed
capsule, must be destroyed to open.
 Is at least one dimension not less than 5
millimeters (0.2 inches).
 Meets test requirements of 173.469.
Test Requirements (173.469)
 Pass
a impact, percussion and bend test.
 Withstand a heat test (1475 F) for ten
minutes.
 Must not leak when subjected to a leach
test.
Normal Form
Any class 7 material not classified
as special form is normal form!
Quantity (Type A)

Type A packaging is the weaker packaging
(cheaper too).
 To be able to use type A packaging for special form,
the quantity may not exceed the A1 value.
 To be able to use type A packaging for normal form,
the quantity may not exceed the A2value.
Quantity (Type B)

Type B packaging is the stronger packaging
(more expensive).
 Type B packaging is required if the special form
quantity exceeds the A1 value.
 Type B packaging is required if the normal form
quantity exceeds the A2 value.
Example 1

A plastic check source 1079 Ci of cadmium-109
(CD-109).
Is it special form?

No, will not pass heat test.
Example 1 (Con’t)

A plastic check source 1079 Ci of cadmium-109
(CD-109).
Does it exceed A2 value? (173.435)

Yes
Example 1 (Con’t)

A plastic check source 1079 Ci of cadmium-109
(CD-109).
 The
material is normal form and exceeds
the A2 quantity therefore it requires type B
packaging.
Multiple Sources
(Sum of Fractions (173.433(d)))

Now suppose we have two or more sources
(different isotopes) in the same package?
 What do we do????
Take the early retirement option?
Or:
Multiple Sources
(Sum of Fractions (173.433(d)))

For each source take the activity divided
by the A1 (or A2)value of that source.
 Then add your answers.
 If the SUM exceeds 1 (one) you must use
type “B” packaging.
Example 2

Normal form commodity sources.
 Look up the A2 value in 49 CFR 173.435.

(HRC)

The amount of radioactive material is great
enough that you are required to obtain a
route from the appropriate state DOT.
 How much is that?
HRC Limits

3000 times A1 or A2
Or

1000 TBq (27,000 Ci)
Whichever is smaller.
HRC Quantity

Always requires a radioactive yellow III.
 Always an exclusive use shipment.
HRC Quantity Example

A type B package with 105 Ci of iridium-192, is
this an HRC quantity?
 1st - what is the A1 value from 49 CFR 173.435
(pg. 578).
 A1= 27
HRC Quantity Example

2nd - multiply 27 Ci X 3000 = 81000 Ci
 Does 105 Ci exceed 81,000 OR 27,000?
No
Then this package IS NOT an HRC quantity.
Limited Quantities

Exception for limited quantities of RAM (173.421).
 Does not have to follow all the packaging, labeling, etc.
 Can not be a hazardous substance or hazardous waste.
 Determined by the activity not the physical size (not more
than allowed by 173.425).
Limited Quantities (Example)
An IM-231A, RSO-5 RADIAC box contains 8 Ci of
Cs-137 in normal form.
 Table 7 says you must not exceed 10-3 A2 value to be
limited quantity.
 The A2 value is 13.5 Ci.
 Then 13.5 Ci X 10-3 = 0.0135 Ci.
 Our source in the units of Ci:

8 Ci = 0.000008 Ci.
Instruments and Articles


contains 80 Ci of Kr-85 in normal form.
 Table 7 says you must not exceed 10-2 A2
value to be limited quantity.
 The A2 value is 270 Ci.
 Then 270 Ci x 10-2 = 2.70 Ci.
