Аннотация:Abstract—The effect of α-particles on one of the simplest unicellular organisms, Synechocystis sp. PCC 6803 cyanobacteria, is studied using a 120-cm cyclotron. Suspensions of cells are irradiated in a cuvette with walls made of thin mylar films. The energy of α-particles in the solution is 24 MeV. The linear energy transfer (LET) of α-particles is close to that of relativistic nuclei of the neon–magnesium group in galactic cosmic rays, making it possible to simulate their effect on biological objects. A number of apparent changes in the
Synechocystis spectral characteristics are found for samples irradiated in and outside a hypomagnetic field.
