A new high-energy neutron therapy facility has been installed at the Douglas Cyclotron Centre, Clatterbridge Hospital, Merseyside, in order to extend the clinical trials of fast neutrons initiated by the Medical Research Council. The neutron beam is

Measurements have been made of beam profiles at 10 cm deep for the neutron beam of mean energy 7.5 MeV produced by the MRC cyclotron at Hammersmith Hospital. Neutron and gamma-ray doses in water were measured with a tissue-equivalent chamber and a Ge

We have measured the biological equivalence of the Clatterbridge neutron therapy beam [p(62)-Be] and the Hammersmith neutron therapy beam [d(16)-Be] using the mouse intestinal crypt assay. The ratio (NDR) of Clatterbridge neutron (n + γ) dose relati

Results of the first randomized clinical trial to compare the effects of fast neutrons and those of x or gamma rays (photons) in treating patients with advanced tumours of the head and neck are reported. In 37 out of 52 patients treated with neutrons

The irregular shape of the human body and the non-uniformity of distribution of elements within the body makes absolute quantitation using in-vivo neutron activation relatively difficult. However, if the mass of an element can be assessed with reason

A calorimeter has been used to measure the absorbed dose in tissue from a beam of fast neutrons. The calorimeter is of the twin type and is made of tissue-equivalent plastic. The calorimeter was calibrated electrically using the electrical resistivit

Experimental results suggest advantages for neutrons where cells are hypoxic, in tumors which are slowly growing and also in a relative sparing of bone damage. The neutrons available at Hammersmith were of 7.5 MeV energy and produced a poorly penetra

Chinese hamster V79 cells have been used to assess changes in RBE of the p(62)Be neutron beam at the Clatterbridge Hospital with depth in a phantom and with use of a hydrogenous filter. The cells were exposed at depths of 2 and 12 cm and at a depth o

Thick plasma samples have been irradiated in air by 2.3 MeV protons for trace elemental analysis by proton-induced X-ray emission spectroscopy. Accurate calibration curves were obtained for Fe, Zn and Sr and detection limits in dry plasma were estima
