2664-2665 / 3107
Film types
- radiation + developer: AgBr crystals
that received dose are converted into
Ag-grains
- AgBr: large over-response for low
energy photons (photo-electric effect)
- sensitive to light (sealing)
- radiation: transparant monomers
opaque polymers
- “Dry” film, “self developing”
- monomer is close to water equivalent,
little energy dependence in megavolt
beams
RadioChromic
RadioGraphic
Examples: Kodak XV-2, EDR
- applicable in “daylight”
- applicable in water
Examples: EBT3, EBT2, EBT,
HS, MD55
