TI  - EFFECTS OF VERY SMALL DOSES OF IONIZING RADIATION AND HYPOMAGNETIC FIELD CHANGE 
      PHYSIOLOGICAL CHARACTERISTICS OF HIGHER PLANT SEEDS.
PG  - 51-58
AB  - Effects of a 40-times weakened geomagnetic field and its combination with low a- 
      and y-radiation doses on the physiological characteristics of higher plant seeds 
      and water redox properties were studied. Germination rate was found decreased and 
      seedlings development retarded equally when exposure to the hepomagnetic field 
      was direct or mediated by water. Besides, water-mediated irradiation by low 
      y-doses moderated and by low a-doses augmented the negative HMF effect on seeds 
      growth. In other words, ionizing radiation dominated in this combination. The 
      redox potential of water (ROP) was noted to rise due to low-intensity a-radiation 
      (9Pu) that was nonlinear and polymodal. Comparing to a-irradiation, the range of 
      ROP changes due to y-irradiation ('37Cs) was narrow which was reflected in growth 
      processes in seeds. Water ROP increases as the magnetic field induction 
      attenuates which implies a natural reduction of water molecules internal energy 
      and bettering of water oxidative qualities. In our view, this was the cause for 
      retarded seed germination. Water is believed to be the determinant for the 
      factors in this study as their effects on seeds were modified by changes in water 
      qualities and structure.
