Claim Text:
1. A method of tracking electromagnetic field, EMF, exposure of a user, comprising: receiving and registering, at a network device, information about the user and information about each of a plurality of user devices associated with the user; identifying, by one of the user devices, the user during use of the user device; estimating, by the user device, EMF exposure associated with use of the user device by the user; transmitting, from the user device to the network device, a value of the estimated EMF exposure together with information identifying the user; revising, by the network device, an aggregated EMF exposure value for the user using the value of the estimated EMF exposure, the aggregated EMF exposure value indicating EMF exposure due to use of the plurality of user devices by the user; comparing, by the network device, the revised aggregated EMF exposure value to a threshold; and transmitting, by the network device to the user device, a signal related to use of the user device if the revised aggregated EMF exposure value exceeds the threshold.
