Question 1
In megavoltage photon beams, which interaction is the dominant contributor to dose deposition in soft tissue?
Correct Answer:
Compton scattering
Question 2
What is the primary function of the bending magnet in a medical linear accelerator?
Correct Answer:
To deflect the electron beam through a specific angle (e.g., 270 or 90 degrees) to hit the target or scattering foil
Question 3
For a 6 MV photon beam, at what depth (d_max) does the maximum dose deposition typically occur in water?
Correct Answer:
1.5 cm
Question 4
In electron beam therapy, what is the approximate relationship between the energy (E in MeV) of the electron beam and its practical range (Rp in cm) in water?
Correct Answer:
Rp ≈ E / 2
Question 5
Which of the following is true regarding the TG-51 calibration protocol for clinical reference dosimetry?
Correct Answer:
It specifies reference dosimetry based on absorbed-dose-to-water calibration factor (Nd,w)
