Abstract

Aim

The thermal neutron, epithermal neutron and high-energy photon fluence were measured in this work around the Varian 21EX 23 MV CLINAC, which is operated in Albairouni hospital in Damascus, Syria.

Background

Photoneutron measurements around medical CLINAC aim to protect both patients and staff from unwanted radiation.

Materials and methods

Neutron and photon activation techniques were applied using gold foils.

Results

It was found that high-energy photons fluence has practically a constant value in the field size. The thermal and epithermal neutron fluence along ox and oy axes has the same order of magnitude.

Conclusion

Gold foils have been used successfully to measure neutron flux and high-energy photons simultaneously using activation techniques.
