Abstract:
System for calculating the exposure to sun radiation received on the different parts of the body by a person, comprising a wearable device (1) that communicates with a telecommunication mobile device (2) and a remote computing unit (3) operatively connected to satellites (4) to receive georeferenced data related to solar irradiation over time and set to associate the solar irradiance data to the geographical position, the posture and the orientation of the person (P) or of parts of the person's body.

Abstract:
The system aims at supplying different users exposing themselves to the sun with a service for control of the erythemal effective UV dose accumulated by each of them starting from a given specific instant, by characterising the photosensitivity of each user before exposure (minimal erythemal dose - MED), carrying out measurement of such doses in real time keeping into account possible changes in the conditions of the environmental UV irradiation and in particular allowing each user to known, at every moment, the dose accumulated by him/her up to that moment and to compare it with a given characteristic critical safety value (threshold) assigned to the user himself/herself. In addition, each user can be personally warned, through a message, about his/her imminent reaching the erythemal-dose threshold, allowing said user to stop sun exposure and at least enabling him/her to avoid the erythemal effects induced by an excessive dose of ultraviolet sun radiation.
Abstract:
A method of determining the minimal erythemal dose (MED) on exposing the skin of a subject to UV radiation, comprising the following steps: irradiating at least one region (P2) of any kind of the body skin of a subject (S) with at least two radiations, each in a different spectral band (a, b), at least one of which is correlatable only or mainly with the melanin amount present in the skin; carrying out the reflectance (or absorbance) measurement relating to said bands at said irradiation point; calculating the value of the minimal erythemal dose (MED) as a function of the measurements carried out. And a device for putting the method into practice.
