Radiation is Used in Industry for Tracers and Thickness Gauges

Question 1

T - What are gamma emitting tracers used in And why?

Answer 1

Industry to detect leaks in the underground pipes

Question 2

T - What is the source allowed to do?

Answer 2

Flow down the pipe and a detector is used above ground

Question 3

T - Why is gamma used?

Answer 3

Because it can pass through any rocks or earth surrounding the pipe

Question 4

T - What happens if there’s a crack in the pipe?

Answer 4

More radiation will collect outside the pipe, and the detector will show extra high radioactivity at that point

Question 5

T - Why should it have a short half-life?

Answer 5

So as not to cause a long-term hazard if it collects somewhere

Question 6

TC - What kind of radiation is used in thickness control?

Answer 6

Beta

Question 7

TC - What do you do?

Answer 7

Direct radiation through stuff being made and put a detector on the other side, connected to a control unit

Question 8

TC - What happens when the detected radiation level changes?

Answer 8

If means the paper is coming out too thick or too thin, so the control unit adjusts the rollers to give the correct thickness

Question 9

TC - Why does it need to be a beta source?

Answer 9

Because then the paper will partly block the radiation

Question 10

TC - What happens if all the radiation goes through (or none)?

Answer 10

Then the reading won’t change at all as the thickness changes
