PostersWe provide world-class research, calibrations, specialised measurement services and training for the dosimetry of ionising radiation in cancer therapy, diagnostics and industrial sterilisation for medicine and pharmaceutics.
Developments in the bio-medical sciences over recent years have involved increased use of high dose gamma irradiation of samples at cryogenic temperatures.
The aim of this work is to improve photon dosimetry in composite fields such as are used in delivering IMRT.
Radiotherapy is one of the most effective treatments for cancer. The success of radiotherapy in curing cancer depends critically on accurate targeting and delivery of the correct radiation dose.
Alanine dosimeters irradiated in industrial electron beams require correction for the near adiabatic rise in temperature during irradiation.
The 3D dose distribution around HDR brachytherapy sources used in cancer treatment is difficult to measure accurately due to the steep dose gradients.
Acetylene has many spectral lines in the 1.55 micron spectral region, and as such has been widely used as a frequency standard for the optical telecommunications C-band.
The aim of this work is to improve photon dosimetry in composite fields, such as those involved in the delivery of IMRT.
The success of radiotherapy is largely down to increasingly complex treatments
The practical realisation of dosimetry standards at NPL is supported by theoretical and computational modelling.
