An apparatus is disclosed that forms a basic integrated radiation shield for a PET isotope production system to create a safe environment. The apparatus and the system combine several subsystems to provide a high degree of integration and a nice aesthetic impression. The apparatus contains a cyclotron system and contains integrated target media handling for gas targets and water dispensing systems for water targets. A compartment including first and second additional radiation shields, respectively, that contains additional processing systems. The apparatus forms a closed radiation-proof system by means of a casing formed of four molded sections. A first and second section constitute a main body containing;the cyclotron system and a third and a fourth section constituting a pair of tight doors for encompassing the cyclotron into a sealed radiation shield. The first section additionally contains a Waste Gas Delay Line embedded in its shielding material.
