“…This has been practically demonstrated [55] and 73 Se was obtained in quantities sufficient for medical applications (see below). Besides low yields of products in -particle induced reactions, there is often another disadvantage that the available -particle beams are of lower intensity than in the case of the proton.…”

“…In order to substantiate the possibility of developing an alternate production route, we considered the reaction 70 Ge( ,n) 73 Se to generate 73 Se. A thin layer of electrodeposited Cu 70 3 Ge alloy on a wedged Cu-backing was irradiated in the internal target system of the compact cyclotron CV28 at an angle of 6.2 ∘ with 28 MeV -particles at a beam current of about 100 μA [55]. After the end of the irradiation the radioselenium was separated by thermochromatography [55].…”

Uses of alpha particles, especially in nuclear reaction studies and medical radionuclide production

Alpha particles exhibit three important characteristics: scattering, ionisation and activation. This article briefly discusses those properties and outlines their major applications. Among others, -particles are used in elemental analysis, investigation and improvement of materials properties, nuclear reaction studies and medical radionuclide production. The latter two topics, dealing with activation of target materials, are treated in some detail in this paper. Measurements of excitation functions of -particle induced reactions shed some light on their reaction mechanisms, and studies of isomeric cross sections reveal the probability of population of highspin nuclear levels. Regarding medical radionuclides, an overview is presented of the isotopes commonly produced using -particle beams. Consideration is also given to some routes which could be potentially useful for production of a few other radionuclides. The significance of -particle induced reactions to produce a few high-spin isomeric states, decaying by emission of low-energy conversion or Auger electrons, which are of interest in localised internal radiotherapy, is outlined. The -particle beam, thus broadens the scope of nuclear chemistry research related to development of non-standard positron emitters and therapeutic radionuclides.
