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
)
huge over-response in large fields
and at large depths
- sensitive to light (sealing)
Examples: Kodak XV-2, EDR
- radiation:
transparant monomers
opaque polymers
- “Dry” film, “self developing”
- monomers close to water
equivalent
little energy
dependence in megavolt beams
- applicable in “daylight”
- applicable in water
Examples:
EBT-XD, EBT3, EBT2,
EBT, HS, MD55
