Radiotherapy using fast electrons, whether alone or in combination with high-voltage, has met with increasing interest in the last few years. This book provides a useful account of the present state of knowledge and critically discusses where an improvement of results is certain or prob able - in contrast to results with radiotherapy using photons alone. The work also considers additional improvements which might be expected to accrue from past experience~ and particular attention is paid to the nature and possible dangers of electron therapy.
