In Vivo Dosimetry

The following table is a guide to select the appropriate detector:

	Photons	Electrons	Cobalt
Entrance dose, few corrections	EDP-10^3G (4-8 MV) EDP-15^3G (6-12 MV) EDP-20^3G (10-20 MV) EDP-HL^3G (16-25 MV)^*1	EDD-2^3G EDP-5^3G	EDP-5^3G (1.25 MeV)
Total body irradiation (TBI)	EDD-5^{3G *2}	-	-
Entrance dose, low perturbation	EDD-2^3G EDP-HL^3G (16-25 MV)	EDD-2^3G	EDD-2^3G
Exit dose	EDD-2^3G Any detector can be used	-	EDD-2^3G
Risk organ monitoring, measurements outside the field	EDD-5^3G	EDD-5^3G	EDD-5^3G
Intracavitary (Teletherapy)	IDF-1^3G	-	-
Brachytherapy	IDF-1^3G (e.g.rectum) IDF-3 (e.g.rectum) IDF-5 (e.g.rectum) IDF-thin (e.g.bladder)

*1 High energy, low perturbation; can be used up to 25 MV

*2 When using spoiler (build-up), otherwise same recommendations as entrance dose, few corrections
