heal.abstract	The regulations for construction in many countries impose the connection of lightning conductors to concrete rebars. In the present work the effect of this connection on the corrosion of rebars was studied in order to avoid connections that accelerate corrosion. In some cases artificial lightning and radioactive lightning conductors were used. It was found that these connections influence the corrosion rate. It depends on the electrical characteristics of the atmosphere that is, on the season and the weather. In most cases the corrosion is accelerated. In some cases the electron flow is inversed, and protection is found. The overall phenomenon for the whole year is an acceleration of the corrosion from 35 to 70%. The artificial lightning and the use of radioactive lightning conductors also accelerate the corrosion. It follows that the grounding of lightning conductors must be separately made with a network to divide the charge of lightning and should not be connected to the rebars.	en
