Nederlandse Commissie voor Stralingsdosimetrie
Netherlands Commission on Radiation DosimetrySubcommittee "Film Dosimetry"
Film is still the most popular 2D dosimeter which
offers a unique spatial resolution. Radiographic film, however, is
subject of controversy in literature and conflicting data have been
reported. The essential point is that this film is oversensitive at low
photon energies. When taking this point into account, a set of
experimental conditions may be derived under which the accuracy of film
dosimetry is acceptable. This goal justifies an NCS report that will
cover the following topics on radiographic film:
- Principles of film dose response to ionizing radiation
- Effects of processing conditions
- Sensitometric curves and dynamic range
- Dose response dependence on depth and field size
- Dose response dependence on film orientation relative to beam direction
- value of film for single beam dosimetry
- value of film for mixed field dosimetry
- practical comparison between XV and EDR2
Parallel topics will deal with radiochromic film that
might have the potential of gradually replacing radiographic film.
Additional attention will be given to
- Film dosimetry for brachytherapy
- Film dosimetry for particle therapy
- Practical phantoms for film dosimetry
- Characteristics of film scanners

Upcoming events
The NCS lustrum
6e lustrum NCS - 5 oktober 2012 | J.A. de Pooter
Vrijdag 5 oktober 2012 viert de NCS haar 30 jarig bestaan. Deze feestelijke dag zal opgeluisterd worden met een eendaags symposium met als thema ‘dosimetrie rondom de patient’. Tijdens dit symposium zal dit thema belicht worden vanuit de verschillende werkvelden: nucleaire geneeskunde, radiologie, stralingsbescherming en radiotherapie Het symposium zal plaatsvinden bij het LUMC in Leiden. Meer informatie over inschrijving en nadere invulling van het programma volgt nog, en zal te vinden zijn op de website.
