Abstract
An electro-optical system intended for medical use that measures and analyses an individual's cumulative short-wave and long-wave UV-radiation exposure as detected by sensor 10 of the system attached to the individual. Sensor 10 separately registers sequences of UV-A and UV-B signals which are synchronized in time by clock pulses. After a predetermined interval sensor 10 is connected to an analyzer unit 12 that statistically processes the collected data to derive risk factor and generate predictive information. Such information permits the physician to predict individual-specific levels of ultraviolet (UV) radiation potentially harmful to the skin and help protect the individual from skin cancer and similar diseases with solar radiation causation.
