Answer 6

Rad therapy

Question 7

What type of imaging does Photodisenigration happen?

Answer 7

Nuclear medicine

Question 8

Relationship between atomic number and scattering

Answer 8

Atomic number increases, photoelectric scattering increases

Question 9

Relationship between patient thickness and scattering

Answer 9

Patient thickness increases, absorption increases, and photoelectric and compton increases

Question 10

What type of scatter is completely absorbed?

Answer 10

Photoelectric

Question 11

Relationship between kVp and scatter

Answer 11

Increase in kVp, increases compton scattering, decreases photoelectric

Question 12

Relationship between linear energy transfer, radiological biological effectiveness and cell survival rate

Answer 12

The highter the LET, the higher the RBE, the lower the CSR
