Therapy device and system and method for reducing harmful exposure to electromagnetic radiation

A treatment system comprising:

• a body adapted to be handheld;
• a controller disposed within said body adapted for receiving information from a head and in response thereto, controlling application of a desired treatment;
• a plurality of heads adapted for being interchangeably mounted to said body, each said head including an energy source for emitting electromagnetic radiation having desired characteristics associated with a desired treatment;
• each said head also including one or more connectors adapted for removable connection with one or more corresponding connectors disposed on said body for facilitating transmission of electrical power from said body to said head for powering said energy source and for facilitating communication of information between said head and said controller;
• and
• at least one of said heads including a proximity sensor adapted for sensing proximity of said head to a surface, said proximity sensor communicating with said controller to control said emission of electromagnetic radiation in accordance with the sensed proximity of said head to said surface.
