  • Title: Biophysical effect of cosmic heavy ions of distinct LET-classes in a plant model system.
    Author: Kranz AR, Gartenbach KE, Pickert-Andres M, Schopper E, Baican B.
    Journal: Adv Space Res; 1994 Oct; 14(10):1021-6. PubMed ID: 11539938.
    Abstract:
    Results presented from recent space flight BION 9 show biological effects of different LET-classes of HZE-particles in different target regions of the seed (meristem and the whole embryo) of Arabidopsis thaliana (L.) Heyhn. HZE-one hit events and non-hit events, i.e. only hit by the low-LET background radiation, and their combined effects on the biological damage endpoint lethality are distinguished. This procedure is opening the opportunity of an approach to comparative studies of the biological effects induced by cosmic HZE-particles of different LET-ranges interacting in the complex cosmic radiation spectrum and with other space flight conditions.
