[A method of estimating the effectiveness of ionizing radiation and magnetic fields for phage induction in lysogenic bacterial culture].
Either the difference delta N of the content of free phage particles in the experiment and the control or K ratio of these values can be used to estimate the effectiveness of ionizing radiation or other agents inducing phage formation in a lysogenic bacterium culture. The estimation technique the results of which are nearly independent of the fluctuations in the number of phage particles in the control, the inductor dose being invariable, is the most adequate one. The induction of phage in E. coli K12 (lambda) culture by X-rays and magnetic field is an example illustrating that the K ratio, which can be called "the induction coefficient", is in a good agreement with the requirement mentioned above. A possible nature of the phenomenon observed is discussed.
