Xray

Question 1

What are the radiation hazard areas when utilizing Golden X-ray systems?

Answer 1

20 feet to the rear, 20 feet to the side, 100 feet to the front

Question 2

What is the maximum radiation exposure aim for X-ray operations?

Answer 2

2 mr or less

Question 3

In most cases what is a good rule of thumb for X-ray stand-off?

Answer 3

Observing good blast and frag stand-offs will provide good X-ray stand-offs

Question 4

What types of X-ray units are there?

Answer 4

Continuous wave or pulse

Question 5

What does KV or KVP mean?

Answer 5

Kilovolt or Kilovolt Peak is the ability of the X-ray machine to penetrate material

Question 6

What is the primary use for the X-ray machine?

Answer 6

To look inside the container and determine bomb components

Question 7

What type of X-ray machine is the Golden X-RAY-200?

Answer 7

Pulse

Question 8

What is the lifecycle of an X-ray tube?

Answer 8

100,000 pulses

Question 9

What is the tube cool down time (in training)?

Answer 9

50 pulses and below 10 sec wait time, 51-99 pulses 5 min wait time

Question 10

What is the optimal distance to place an X-ray panel behind a target?

Answer 10

1/4-1/2 inch

Question 11

What is the inverse square law?

Answer 11

2x the distance 4x the exposure, the 2x4 rule

Question 12

How does the X-ray panel work?

Answer 12

When exposed to the X-rays, the phosphor screen captures the energy of the X-rays and stores the pattern as a latent image

Question 13

What radioactive isotope is inside the Golden XR-200 X-ray machine?

Answer 13

It does not contain a radioactive isotope

Question 14

What is the beam angle of the XR-200 X-ray machine?

Answer 14

40 degrees

Question 15

What is the effect when the phosphorus screen is placed 1 foot behind the package?

Answer 15

Items appear larger

Question 16

What percentage of the X-ray energy generates heat?

Answer 16

99% and 1% X-Ray

Question 17

What is the X-Ray’s primary purpose

Answer 17

Give the ability to look inside a container

Question 18

What type of isotope is located within the source of the x-ray system

Answer 18

The x-ray system does not contain an active isotope

Question 19

How are x-rays produced for the EOD source

Answer 19

Energy is fired onto tungsten which produces x-rays

Question 20

What degree of cone is projected from the EOD source

Answer 20

40 degrees

Question 21

What level of radiation exposure is acceptable

Answer 21

2mR/hr

Question 22

Which is a greater danger, frag/blast or X-ray radiation

Answer 22

Blast and frag

Question 23

What is a KvP and what occurs when it is increased

Answer 23

Kilovolt peak

Penetrating power increases as KvP increases

Question 24

What is a benefit of using continuous X-ray

Answer 24

You are able to select the level of energy

Question 25

What are the types of source units

Answer 25

Continuous and pulse

Question 26

On a pulse system, how long will the tube last

Answer 26

100k pulses

Question 27

What is the optimum distance from the device for the x-ray panel

Answer 27

1/4” - 1/2”

Question 28

What is the inverse square law

Answer 28

2x4 = 2x the distance, 4x the pulse

2’ @ 20 pulses = 40mR
4’ @ 80 pulses = 40mR
8’ @ 320 pulses = 40mR
16’ @ 1240 pulses = 40mR

Question 29

How do phosphors panels work

Answer 29

The phosphor panels capture the x-ray energy and stores the pattern as a latent image
