transportation

Question 1

when you receive a package, how do you test for radiation?

Answer 1

ionization chamber at 1 m

wipe test on the surface of the shipping container

Question 2

if a package with radioactive material is damaged, what is the next step?

Answer 2

altert the radiation safety officer

Question 3

radiation at 1 m must fall below what value?

Answer 3

radiation must fall below the transportation index, which is located in a small rectangular box towards the bottom of the label (the label is diamond shaped)

Question 4

you receive a package with radioactive materials and the radiation level is above the transportion index, next step

Answer 4

alter your radiation saftey officer and await further instruction

Question 5

how do you perform a wipe test on a shipped box with radiactive material?

Answer 5

surface wipe over 300 cm2, and put wipe in a well counter to assess for radiation.

this is often called removable radiation

Question 6

limits for wipe test

Answer 6

generally 220 disintegrations/min/cm2. If greater than this value you notify the radiaiton safety officer.

can open it is 22 dpm/cm2

Question 7

after you pass the 1 m ionization test and the surface wipe test (when receiving a shipment of radioactive material) what is the next step?

Answer 7

remove the packing label and ensure the right substance was delivered to the right place –> confirm inner contents match what is on the label

Question 8

For how long do you need to keep receipts of radioactive substance shipments?

Answer 8

3 years (according to NRC)

if in an agreement state, may need to hold records longer

Question 9

What is an agreement state?

Answer 9

primary oversight over radioactive materials, and can’t have rules that are less strict than NRC but can have rules that are more strict

Question 10

in a non-agreement state, who oversees radiactive by-products?

Answer 10

NRC automatically oversees reactor by-product materials such as Tc-99m or I-131

Question 11

who oversees cyclotron produced materials?

Answer 11

indiviual states (not the NRC, even in non-agreement state)

F18 or I-123

Question 12

What are the types of labels for radioactive materials?

Answer 12

White 1

Yellow 2

Yellow 3

white 1 < yellow 2 < yellow 3 (in order of radiation intenisty)

Transportation index (at 1m measured with an ion chamber):

• White 1 = 0 mrem/hr
• Yellow 2 = <1 mrem/hr
• Yellow 3 = 1-10 mrem/hr

Question 13

Transportation index (at 1m measured with an ion chamber):

White 1 =

Yellow 2 =

Yellow 3 =

Answer 13

Transportation index (at 1m measured with an ion chamber):

White 1 = 0 mrem/hr

Yellow 2 = <1 mrem/hr

Yellow 3 = 1-10 mrem/hr

Question 14

how do you ship something with a transportation index > 10 mrem/hr

Answer 14

exclusive use provisions

Question 15

what is the max radiation level at the surface for the following labels:

White 1 =

Yellow 2 =

Yellow 3 =

special provision =

Answer 15

what is the max radiation level at the surface for the following labels:

White 1 = 0.5 mrem/hr

Yellow 2 = 50 mrem/hr

Yellow 3 = 200 mrem/hr

special provision = up to 1000 mrem/hr

Question 16

Based on NRC guidelines, how should a medical officer report an NRC defined “medical event”

Answer 16

Via telephone by the next day

both the patient and referring physician should be notified within 24 hours

within the next 15 days a formal written report should be submitted tot he appropriate NRC regional office

the formal written letter should include:

• the licensee name,
• prescribing physician name,
• brief description of the event,
• why the event occurred,
• the effect on the individual receiving the administration,
• what actions have been taken or are planned to prevent recurence,
• and certification that the licensee notified the individual

Question 17

annual dose limit to a member of the general public

Answer 17

100 mrem (1mSv)

2 mrem/hr (0.02 mSv/hr)

Question 18

background annual radiation dose

Answer 18

300 mrem (3 mSv)

Question 19

total effective occupational dose limi for a radiation worker

Answer 19

5000 mrem

50 mSv

(roughly 15 x the average background radiation dose to a member of the general public)

Question 20

dose limit to radiation worker’s extremity

Answer 20

500 mSv

50,000 mrem

Question 21

in what time frame should a survey be performed when receiving a radioactive package?

Answer 21

within 3 hours of receiving the package if received during normal business hours

Question 22

if a radioactive shipment is delivered after hours or on the weekend, what is the appropriate protocol?

Answer 22

must be assessed within 3 hours at the start of the following business day

Question 23

how long must records for radioactive packages be kept

Answer 23

3 year minimum.

Some aggreement states hae a min of 5yr

Question 24

multiple packages shipped together should not exceed

Answer 24

50 mR

Question 25

what is a completely unacceptable surface radiation

Answer 25

>6600 dpm/300cm2

contact both the shipper and NRC if beyond allowable limits
