Apparatus (), systems and methods are disclosed for treating a biological fluid with light. A container () of biological fluid is introduced into a fluid treatment chamber () where it is contacted with light provided by one or more light sources () in proximity to the fluid treatment chamber (). A light sensing system () senses the intensity of illumination of the light. A radiometer () may be inserted into fluid treatment chamber () to calibrate the light sensing system (). An electronic control system () utilizes an interface circuit board () to interface a computer circuit board () to a display panel (), a user interface panel (), a relay circuit board (), light sensorsand various other sensors (). A detector () senses agitating movement of a tray () that contains biological fluids. Methods include calibrating (-), sensing (-) and correcting (-) light intensity measurements, and determining the length of treatment () to reach a desired illumination dose. A radiometer () is equipped with a plurality of light sensors () disposed on both sides to measure light intensity in chamber () and to provide a reference for calibrating light sensing system ().
