[ RadSafe ] Leakage radiation measurements in clinical electron beams

[Dr. Sergio Faermann]

Dear colleagues
 
We are performing an evaluation of the leakage radiation levels of the
electron beams available in our Clinac DHX accelerator ( Clinac 2100
C/D)
1-We would like to know what are the permissible leakage levels for
electrons?
2-What is the definition of penumbra for electron beams?
3- How you define the field size for electron beams, when you perform
film measurements ?
 
Thanking you in advance
