1. An integrated shielded system for Positron Emission Tomography isotope production constituting a casing, comprising: a first compartment inside the casing containing a cyclotron device including standard subsystems;  a second compartment including a plurality of sub-compartments comprising:  a first sub-compartment for handling gas targets consisting of valve and pressure gauges;  a second sub-compartment for water dispensing systems for water targets;  a third sub-compartment including a first additional radiation shield and containing additional processing systems including valves, pressure and flow sensors, ovens and inside the first additional radiation shield; and  a fourth sub-compartment including a second additional radiation shield containing additional processing systems and valves, pressure and flow sensors, and ovens inside the second additional radiation shield;  a third compartment containing a secondary cooling system, a main power distribution, a vacuum system controller and an ion source gas control; and  wherein the system constitutes a closed radiation-proof system by means of a casing consisting of four molded sections, wherein a first and a second section constitute a main body containing said first compartment and a third and a fourth section constitute a pair of closing doors for encompassing said first compartment into a sealed radiation shield, whereby said first section additionally contains a Waste Gas Delay Line embedded in shielding material of the first section. 2. The system according to  claim 1 , wherein the four sections consist of a dense concrete designed to balance attenuation properties and a volume/weight ratio of the shield, and further comprising a ballast formed mainly of magnetite for high gamma attenuation and containing additional Boron and Hydrogen components to strengthen a neutron attenuation capacity. claim 1 3. The system according to  claim 2 , wherein the Waste Gas Delay Line consists of a plastic tube formed into a coil to obtain a proper gas delay and embedded into the concrete material of the first section of the casing. claim 2 4. The system according to  claim 2 , wherein the third and fourth section constituting a pair of closing doors are suspended on roller bearings in hinges, whereby a portion of each hinge is fixedly molded into the concrete forming the first and third sections or second and fourth sections, respectively. claim 2 5. The system according to  claim 1 , wherein the first and second additional radiation shields are formed by a sandwich type shielding containing plastics and lead. claim 1 6. An apparatus constituting an integrated Positron Emission Tomography isotope production system comprising: a first compartment containing a cyclotron device including vacuum pumping systems, targets, target support systems, cooling water systems and target window cooling systems;  a second compartment including a plurality of sub-compartments comprising:  a first sub-compartment for handling gas targets consisting of valve and pressure gauges;  a second sub-compartment for water dispensing systems or water targets;  a third sub-compartment including a first additional radiation shield and containing additional processing systems including valves, pressure and flow sensors, and ovens inside the first additional radiation shield; and  a fourth sub-compartment including a second additional radiation shield containing additional processing systems and valves, pressure and flow sensors, and ovens inside the second additional radiation shield;  a third compartment containing a secondary cooling system, a main power distribution, a vacuum system controller and an ion source gas control; and  wherein the system constitutes a closed radiation-proof system by means of a casing consisting of four molded sections, whereby a first and a second section constitute a main body containing said first compartment and a third and a fourth section constitute a pair of closing doors for encompassing said first compartment into a sealed radiation shield, whereby said first section additionally contains a Waste Gas Delay Line embedded in shielding material of the first section. 7. The apparatus according to  claim 6 , wherein the four sections consist of a concrete designed to balance attenuation properties and a volume/weight ratio of the shield and further comprising a ballast formed mainly of magnetite for high gamma attenuation and containing additional Boron and Hydrogen components to strengthen the neutron attenuation capacity. claim 6 8. The apparatus according to  claim 7 , wherein the Waste Gas Delay Line consists of a plastic tube formed into a coil to obtain a proper gas delay and embedded into the concrete material of the first section of the casing. claim 7 9. The apparatus according to  claim 7 , wherein the third and fourth section constituting a pair of closing doors are suspended on roller bearings in hinges, whereby a portion of each hinge is fixedly molded into the concrete forming the first and third sections or second and fourth sections, respectively. claim 7 10. The apparatus according to  claim 6 , wherein said first and second additional radiation shields are formed by a sandwich type shielding containing plastics and lead. claim 6
