Question 12

Question

Match the description of nuclear decay to the type of nuclear decay.

Column A
1.
4/2 He
2.
0/-1 e
3.
0/0Y


4.
Can be stopped by paper:
Can be stopped by paper
5.
Can be stopped by aluminum:
Can be stopped by aluminum
6.
Can be stopped by lead:
Can be stopped by lead
Column B
a.Gamma
b.Beta
c.Alpha

Answer 1

To match the description of nuclear decay to the type of nuclear decay, here is the correct pairing:

Column A

1. 4/2 He - c. Alpha
2. 0/-1 e - b. Beta
3. 0/0 Y - a. Gamma

Column A (Descriptions of stopping power): 4. Can be stopped by paper: - c. Alpha (Alpha particles can be stopped by a sheet of paper.) 5. Can be stopped by aluminum: - b. Beta (Beta particles can be stopped by aluminum.) 6. Can be stopped by lead: - a. Gamma (Gamma rays require lead or other dense materials for significant attenuation.)

So the final pairs are as follows:

1. c. Alpha
2. b. Beta
3. a. Gamma
4. c. Alpha
5. b. Beta
6. a. Gamma
