Neutron capture therapyheir discovery some 37 years previously. Many of the biological effects of ionizing radiations, not only of roentgen rays but also of the radiations from radium and other radioactive elements, were therefore known and it was logical to look immediately for uses in medicine of the new particles of ma

Dosimetry less complex, leading eventually to a more stable configuration. The probability λ of this process occurring within a unit interval of time is characteristic of the nuclear species and it is independent of the length of time during which the radioactive nucleus has been in existence. The value of λ

Irradiation with open (incorporated) radio-isotopesutic radiological problems. Even more realistically, especially from an economic viewpoint, the availability of the products of the chain reactor in the middle 1940’s seemed to open up much wider vistas in the field of radiation therapy. Now one was offered an assortment of isotopes of practically a
