Mobile building unit as well as a building and a method for constructing the building

Abstract

The invention relates to a mobile building unit which is assembled to a building including at least one room ( 3 ) enclosed by walls ( 6 ), a roof ( 7 ) and a floor ( 12 ) for accommodating radiating equipment ( 5 ) and for treatment, therapy or diagnosing by means of ionizing radiation. The walls, the roof and floor of said building ( 1, 1 ′) serve as a radiation shielding barrier for preventing radiation at health-impairing levels from escaping to the outside of the building structure. At least two of the walls and the roof of the building, has the form of a double walled structure comprising an inner ( 8 ) and an outer ( 9 ) partition element with a space ( 10 ) therebetween. The building also has a filling inlet through which the space is fillable with a fillable material, in order to reduce weight and facilitate transportation of the assembled building with the space in an emptied state, and to allow filling of the space with the fillable material once the building is located at a site, where it is to be used, to provide a radiation shielding barrier with a sufficient shielding capacity. The invention also relates to a method for constructing the same.

         7 . A building including at least one room ( 3 ), enclosed by walls ( 6 ), a roof ( 7 ) and a floor ( 12 ), for accommodating radiating equipment ( 5 ) for treatment, therapy or diagnosing by means of ionizing radiation, the walls, the roof and the floor of said building ( 1 ,  1 ′) serving as a radiation shielding barrier for preventing radiation at health-impairing levels from escaping to the outside of the building structure, wherein at least two of the walls and the roof comprises a double walled structure comprising an inner ( 8 ) and an outer ( 9 ) partition element with a space ( 10 ) defined therebetween, and a filling inlet through which the space is fillable with a fillable material to allow filling of the space with the fillable material once the building is located at an operating site, where it is to be used, to provide a radiation shielding barrier with a sufficient shielding capacity.  
     
     
         8 . A building according to  claim 7 , wherein the space ( 10 ) forms a closed, liquid impermeable tank.  
     
     
         9 . A building according to  claim 8 , wherein there are two or more separate tanks ( 10 ) in the building.  
     
     
         10 . A building according to  claim 8 , wherein the tank ( 10 ) contains water.  
     
     
         11 . A building according to  claim 8 , wherein it comprises a system for monitoring the water level.  
     
     
         12 . A building according to  claim 8 , wherein it comprises a system for temperature control of the water.  
     
     
         13 . A building according to  claim 7 , wherein the spaces ( 10 ) contains sand.  
     
     
         14 . A building according to  claim 7 , wherein it is adapted for treatment of humans.  
     
     
         15 . A building according to  claim 7 , wherein it is assembled of two or more building units ( 1 ,  1 ′).  
     
     
         16 . A building according to any of the claims  7 - 15 , wherein at least three of the walls and the roof comprises a double walled structure.
