Semiconductor detectors based on p-type silicon but with different doping levels have been investigated. The linearity response with dose rate (dose per pulse in a pulsed beam), the sensitivity drop and the sensitivity variation with temperature have

The TMS-Radix treatment planning system by Helax has been used in clinical practice at the University Hospital in Uppsala for more than a year. As Uppsala was one of the two test sites for TMS, an extensive test program was undertaken before the syst

The synchrocyclotron at the The Svedberg Laboratory (TSL) in Uppsala is now reconstructed and can presently operate with fixed frequency and proton energies up to 100 MeV. A first treatment room with a narrow proton beam unit for therapy of eye tumou

Fifty-three patients with small cell carcinoma of the lung were treated with chemotherapy and radiotherapy, 40 Gy in the chest tumour. Intrathoracic failure occurred in 89% of the cases with extensive disease and in 60% of those with limited disease.

Semiconductordetectors have frequently been used in vivo dosimetry (IVD) to confirm the dose given to a patient in external radiotherapy, due to the high mechanical stability, small size, high signal and no need of external bias. As it is important t

Depth dose measurements in continuous cobalt radiation and pulsed roentgen rays were performed with nonirradiated and preirradiated detectors made of n-type silicon. A change in the relative signal at 15 cm depth of 5 to 10 per cent was found in puls

p-silicon semiconductor detectors were partially shielded with lead filters of various geometries with the purpose to minimize the quality dependence in assessments of depth dose distributions in large fields of cobalt radiation. It is shown that a l

Comparison of depth ionization distributions from a silicon semiconductor detector and depth dose curves from a plane parallel ionization chamber show that a semiconductor detector of p-type is well suited for relative electron dosimetry in the energ

Silicon semiconductor detectors used in radiation dosimetry have different properties, just as e.g. ionisation chambers, affecting the interaction of radiation with matter in the vicinity of the sensitive volume of the detector, e.g. wall materials,
