Different qualities of radiation are known to cause different biological effects at the same
absorbed dose. Enhancements of the biological effectiveness are a direct consequence of …

A brief review is given on some parameters and physical effects which influence the
mechanism of proportional counters. The following topics are discussed: gas amplification …

An algorithm for the derivation of LET-distributions from pulse-height spectra obtained with
proportional counters is described. The method is based on Fourier transformation: it is …

The characteristic peak in the gain versus pressure curve, observed experimentally by some
workers using low pressure proportional counters, is shown to be due to the Townsend …

The FeSO 4 G-value for a therapy beam of 14 MeV neutrons from a DT generator has been
measured, using a polythene-ethylene ion chamber for basic dosimetry. The result for the …

Publisher Summary This chapter presents a rationale for fast neuron therapy and illustrates
the relationship between radiosensitivity and oxygen tension. It also discusses skin reaction …

Radiotherapy uses radiation for the diagnosis and treatment of disease, in particular cancer.
To understand and improve radiotherapy techniques, an accurate understanding of energy …

This work demonstrates new avenues for their quantitative characterization of dosimetric
distributions based on the underlying spatial distribution of data via texture analysis. Monte …

Different qualities of radiation are known to cause different biological effects at the same
absorbed dose. Enhancements of the biological effectiveness are a direct consequence of …

[en] The relative biological effectiveness of fast neutrons for damage to organized tissues in
experimental animals is discussed. Information about basic mechanisms through which …
