according to this model a quantity of aberrant cells changes with the concentration of thiophosphamide non-linearly and can be described according to the equation a=exp [ - ( kc+alpha ) 2 ] , where a is a portion of normal cells , c - a concentration of a mutagen , k and alpha - the coefficients , while exp [ -alpha2 ] is the control level of normal metaphases .
