ABSTRACT:
The present invention relates to a portable computing device comprising, in known manner, means for adding digital information, means for determining periods of time and display means, wherein it also comprises a nuclear detector adapted to deliver electrical signals whose amplitude spectrum depends biunivocally on the energy spectrum of the radiation in which it is placed and means for converting these signals into digital information, the addition means receiving said digital information, the means for determining periods of time controlling said addition means so as to make a calculation of the dose of nuclear radiation received during a period of time, called integral dose, which is displayed by said display means. The invention is more particularly applicable in the domain of protection against radiation, or health physics.
