IntroductionThe following presentation....

• Provides information on receiving Class 7 Radioactive Material

• Acts as a refresher for staff working in areas where radioactive material is received

• Serves as part of a radiation safety orientation program for new employees

Key Objectives

• Understand the shipping and delivery requirements for Class 7 Radioactive Packages.

• Identify the requirements of an initial inspection before opening a radioactive package.

• Use proper radiation safety practices when opening radioactive packages.

• Understand the requirements for record keeping.

• Identify the required regulatory reporting requirements when receiving radioactive packages.

Receiving Requirements

Shippers are required to package and provide the following for each Class 7 shipment.

Approved Shipping Container

Correct TDG Package Type (UN# and Name (Excepted or Type A)

Correct Labelsradiation warningshipping address

packing documents

Identified Isotopes and Activity Limits


No person, other than the consignor (shipper) or the consignee (receiver) of the package, shall open the

package unless....

a) measures are taken to prevent persons from receiving doses higher than the radiation dose limits prescribed by the Radiation Protection Regulations

b) the package is opened in the presence of an expert in radiation protection (someone authorized and trained to open the package)

Verify Address

Before signing for the package, verify if it is for your department. If not, then do not accept the package.

If you sign, and it is not for you, you are responsible for the package. This could cause problems if you sign for a package and the hospital does not have the isotope on their licence.

Worth repeating 10

Deliver – Store Promptly

You may take direct receipt from a courier during daytime deliveries.

Procedures for after hours receipt of a shipment, by security, includes examination for any damage or leaks and signing for the package. Once signed for, the package is delivered to an after hours holding area. The department responsible for the package is to pick it up the next day.

11

Opening a Package


Check for Damage

Perform a visual inspection of the shipping container for any evidence of damage, leakage or tampering.

If the package is damaged, tampered with or leaking, stop all receiving and implement emergency procedures. Also notify the Radiation Safety Officer.

12

Opening a Package


Open Package in Designated Area

Use a fume hood if the material is volatile such as iodine

Open package behind appropriate shielding for a high level of activity

Use a bench top in a designated radiation work area

13

Opening a Package


Use Personal Protective EquipmentWear appropriate Personal Protective Equipment (PPE) for the shipment received such as...

buttoned lab coat

The ring is to be worn under the gloves

to protect it from contamination.

Opening a Package

Verify Package Dose Rate

If a survey meter is available, monitor the dose rate at the surface and 1 meter around the package and note any discrepancies with the shipping documents.

Most nuclear substance labs only have contamination monitors (pancake probe) available so external monitoring is not required as the probe is generally not able to accurately measure dose rate. Check with your department medical physicist on this matter. 15

Opening a Package


Verify Package Contents

Once the package has been opened verify the nuclear substance, the quantity and other details with the information on the packing slip and with the purchase order.

16

Measuring Contamination

The Wipe Test

17


Prepare, in advance, any material to conduct your wipe test such as…. • filter paper• Q-tips or alcohol swabs• Tongs• numbered counting vials• water or alcohol if using dry

swabs.


18

It is acceptable to use one wipe to test all package components for contamination.

If no contamination is present, you can log in the shipment, store the vial and dispose of the packaging

IF the single wipe is contaminated, repeat the procedure with separate wipes for each package component to isolate where the contamination is located.

Some procedures wipe all package components with separate wipes from the start, which is acceptable.



19

The minimum required by regulations is to wipe the exterior surface of the primary container and all six sides of the outer

container.

The CNSC has clarified that it is expected that the wipe now includes all six sides of the

package. (Radiation Safety Information Sheet 62.0 Receiving Radioactive

Packages)

* may need to hold container with tongs if a high beta or gamma emitter or required by

department procedure



The primary container is the main component that holds the nuclear substance. Generally for liquid vials, it is the glass vial or inside of the lead pot. If you generally just handle the lead pot then this can be considered the primary container. 20

exterior surfaces of the lead pot

interior surface of the lead pot




Other components may be wiped but generally these do not have to be done if the primary container or outside box is not

contaminated.

21

You should have a predetermined count rate to meet the wipe test criteria of 4

Bq/cm2




Ensure that your liquid scintillation, gamma counter or contamination meter are on appropriate settings to count

your wipes.22



A clean or “control” wipe should also be used as a background count

Example: You may know that 340,000 cpm = 4 Bq/cm2 for P-32 being counted on the well counter in Room 4023. This count may be 260,000cpm on a pancake meter in the lab for the same isotope.

The Final Steps

24

Used vials containing the wipe test samples are

placed in an appropriate radiation waste storage

container to await disposal


Finish Receiving

Waste Disposal

25

If your wipe tests on the package and packing materials are

negative any reference to “radioactive” must be defaced or removed

before disposing of packaging.

Finish Receiving

Discarding Package Material


26

With both hands gloved, peel one glove off from top to bottom and hold it in the gloved hand

With the exposed hand, peel the second glove off from the inside, tucking the first glove inside

the second

Dispose of the gloves promptly

Never touch the outside of the glove with bare skin and wash hands as soon as possible

with next steps

Inventory EntryIsotope Name, Activity, Chemical Form, Lot Number.

Results of Receiving Inspection


Log the shipment receipt on the

inventory log in your records binder or electronic system


Generally this includes the lot number, activity, volume,

isotope, calibration date, receiving

Emergency/Reportable Events

Notify the Radiation Safety Officer if any receiving requirements are not met such as:

• incorrect address or delivery if the package was already received• incorrect labels or transport index• radiation levels in excess of labeling or >2mSv/hr at

surface•package damage, leaking or evidence of tampering•wipe test reading above licence criteria of 4Bq/cm2

•lost shipments32

We all have responsibility for safety in the workplace

and saying ‘’it is not my job’ doesn’t cut it when it comes to radiation safety.

The end.....now you can do the quiz

When in doubt call your supervisorYou will never be in trouble for asking questions or asking for help when it comes to radiation safety.
