[en] The public of the XXI century is avid one to obtain information on the advances of the science and the technique and their impact in the daily life, for it has it a powerful arsenal of means that constantly transmit all that being of interest can for the big masses. However the technical complexity of the information that is transmitted and the sensationalist intentions with which they are managed it can in many cases to distort their scientific rigor and to misinform to the public in question. The Nuclear energy from their emergence, and for the disastrous consequences of their initial use with warlike ends, it has been target of those more diverse manipulations and misrepresentations in a such way that it left generating a strong oppositor current together with their development. It is for it that the International Atomic Energy Agency recommends to all the countries members that together with the development of the applications of the nuclear energy one works in the information to the public on those risks and benefits of the use of the same one. This recommendation this in full agreement with the intentions of Cuba of elevating the population's integral general culture systematically and for it the authors of this work designed a course that with the Title of 'The Radiations and the Life', it was proposed at the corresponding levels to be transmitted by National Television in the mark of the program 'University for All'. The present work exposes the experience of the authors in the realization of this course, the same one represented a challenge for the specialists of very high qualification that were responsible for the elaboration of a pamphlet or tabloid with the contents of the course and that they imparted the conferences in the popular television program. An important and novel element of this course was the dialogue established with the public through the Electronic mail: radiacionesyvida at cnsn.cu that stayed flowingly during the time in the one which the course came out to the air and that it was able to respond a considerable number of queries formulated by televiewers of the more wide spectrum as for its professional formation and cultural level. The good results of this course are an example of the paper that corresponds to play the scientists and specialists in the popularization of the more strict scientific truth with a guessed right balance of the risk-benefit and far from the sensationalism and the speculation with which the capitalist press, habitually manages this information to the public.
