Depending on the mechanism of interaction, we speak of direct and indirect ionizing radiation. The first group includes electrically charged particles (alpha, beta, protons), which ionize mainly by Coulomb interactions. On the other hand, neutral particles (e.g. neutrons) and high-energy electromagnetic radiation (X and. rays) interact with matter indirectly through the photoelectric effect, Compton scattering, electron-positron pair production, and also by nuclear reactions. The paper presents the result of an experiment in which seeds Lepidium sativum L. were exposed to neutron radiation. A commercial Cf-252 neutron source was used in the experiment (source activity on the day of the experiment A = 11 MBq, yield of neutron source W = 1.34E + 6 n/s,) [5-7]. The exposure time ranged from 5 seconds to 11 hours.plinfo:eu-repo/semantics/closedAccessneutronsexposureseedsgerminationArticle10.15199/48.2022.12.6098122622662-s2.0-85143172358Q4WOS:000905602700060N/A
