[Microcinematographic study of the lengthening of the cell cycle after x-ray and fast neutron irradiation].
The median cycle duration of unirradiated EMT6 cells is equal to 9.68 +/- 0.20 h. It reaches 10.77 +/- 0.42 h, 12.95 +/- 0.62 h, 14.95 +/- 1.10 h, 16.15 +/- 1.87 h and 20.25 +/- 2.25 h after 250 kV X-rays doses of 1 Gy, 2 Gy, 4 Gy, 6 Gy and 8 Gy respectively and 11.23 +/- 1.03 h, 13.40 +/- 0.53 h and 15.13 +/- 1.15 h after p(65) + Be neutron doses of 0.75 Gy, 1.5 Gy and 2.5 Gy respectively. The corresponding mitotic delay (Tc irradiated - Tc controls) may be evaluated equal to congruent to 1.15 h per Gy for X-rays and to congruent to 2.30 h per Gy for neutrons.
