Technical Data Sheet
Issued 2015-04
Oncology EDR2 Film
Oncology EDR2 Film is a high-contrast film that is coated on both sides with a very fine grain emulsion having low
image noise. It is excellent for relative dosimetry (e.g., field uniformity, equipment characterization: field shapes,
port openings, multi-leaf collimators).
With the user’s appropriate calibration and maintenance of equipment, film may be applicable to absolute dosimetry
applications such as high dose treatment strategies including intensity-modulated radiation therapy (IMRT).
Wide response range:


Approximately linear
Robust processing
Available in convenient READY PACK format
The film may only be directly exposed for calibration and dosimetry purposes without use of an intensifying screen.
It is not to be used for patient imaging, localization or verification.

Storage and Handling
Storage Unexposed:
10–24 °C (50–75 °F)
Do not refrigerate or freeze as this can cause condensation to
occur.
30–50 %RH
Protect from heat and radioactive sources. Film is to be
properly shielded from x-rays, gamma rays, or penetrating
radiation.
Exposed:
Keep cool, dry, and properly shielded from penetrating radiation. Process as
soon as possible.
Processed:
16–27 °C (60–80 °F), 30–50 %RH
The film should be used before the expiration date
indicated on the box with the lot (emulsion) number
Handling Hands must be clean, dry and free of lotions, etc. Film should be handled carefully by the edges to avoid
physical strains such as pressure, creasing, or buckling. Luminous watches, cell phone and darkroom light
leaks should be avoided.
Do not re-use. Film is a single use medical device.
