Definitions

  • the present invention relates to a mobile building unit including at least two walls, a roof and a floor, which is movable to an operating site and assembled there to form a building including at least one room defined by at least four walls, a roof, and a floor.
  • the invention also relates to a building including at least one room, enclosed by walls, a roof and a floor, for accommodating radiating equipment for treatment, therapy or diagnosing by means of ionizing radiation, wherein the walls, the roof and the floor of said building serve as a radiation shielding barrier for preventing radiation at health-impairing levels from escaping to the outside of the building structure.
  • the invention also relates to a method for constructing a building including such a room.
  • radiating equipment such as equipment for X-ray imaging, radiation surgery or therapy, or radiation sterilization of various products such as e.g. foods or material
  • the radiation shielding is normally accomplished by constructing the walls, roof and floor of the room, where the equipment is located, of very thick concrete, often in the order of about 500 mm or thicker. For an existing building this necessitates an extensive reconstruction.
  • the equipment often is very heavy, e.g. equipment for radiation surgery weighs about 20 tons, it may require reinforcement of the floor structure.
  • the radiation equipment normally is accommodated in a separate building, either as a completely freestanding building or connected to another building, such as a main building of a hospital.
  • constructing a completely new building of concrete is elaborate and time-consuming and involves planning, foundation work, concrete casting of the building structure, installation of water pipe system, electrical system, communication system, temperature control system and ventilating system, inner and outer covering of the walls, roof and floor including insulation if any, as well as installation of the radiation equipment in the completed building. Altogether this is a process which often is extended over a period of six months or more.
  • One object of the invention is to provide a mobile building unit which easily and quickly can be assembled to serve as a radiation shielded building for accommodating radiating equipment.
  • the invention also refers to a building with essentially the same object as above.
  • the invention also refers to a method which facilitates constructing of a building adapted for accommodating radiating equipment.
  • the invention is based on the understanding that the above-mentioned objects can be achieved by constructing the building in form of one or more mobile building units, wherein at least two of the walls and the roof of the building units are designed with an outer and an inner partition element with a space or an accommodation between the partition elements, adapted to be filled with a fillable radiation shielding material.
  • the fillable material can be added after the building units are already in place at the operating site, the units are easily transportable in an empty state. Therefore, the units can be manufactured at an industry plant or construction site, remote from the final location or operating site of the building, and thereafter transferred to the operating site and assembled there.
  • the foundation work at the operating site may be prepared so that when both the foundation work and the units are completed, the units are transferred to the operating site and assembled.
  • the spaces between the inner and outer partition elements may be filled with any fillable material capable of providing radiation shielding when contained within the spaces between the partition elements in the building units.
  • suitable filling material include liquids, e.g. water, or a particulate or grain shaped solid bulk material, e.g. sand.
  • the units By letting the fillable material form an essential or a main part of the radiation shielding barrier between the radiation equipment and the environment, the units will have a comparatively low weight in a state where the spaces in the walls, the roof and possibly the floor are unfilled. This enables transport of the units by truck, train or boat from the construction site to the operating site. Not until the units are installed and assembled at the operating site, the radiation shielding is arranged by filling the fillable material in the spaces in the building units.
  • the radiation shielded building may be formed in one single unit but generally, the required size will make it advantageous to assemble the building by connecting two or more mating units to each other.
  • the radiation shielded building is composed of two mating, “container-like” building units forming a radiation shielded treatment room for treatment of a patient.
  • the building also comprises an operator room accommodated in a third building unit, but that third building unit need not be radiation shielded since no radiation is generated in the operator room.
  • the wall between the operator room and the treatment room must of course be radiation shielded. In the preferred embodiment this has not been accomplished by a fillable material in a space in the wall, but through a sandwich wall structure with absorbing metal plates, e.g. steel plates.
  • the width of the space in the walls, roof and possibly the floor is dependent on for instance the type of radiation, the radiation intensity and the type of material used as a fillable material.
  • water is used as a fillable material in a building adapted for radiation surgery with gamma-radiation and in that case a space of between 500 to 1500 mm is generally sufficient.
  • the spaces in the walls, roof and possibly the floor of the building preferably are formed as closed spaces or “tanks” to prevent leakage or evaporation of the water.
  • a thin layer of insulation is arranged on the inside as well as the outside of the walls and roof.
  • the water in the spaces may be connected to a temperature controlling system for warming the water during the cold season and possibly cooling the water during the warm season.
  • the water in the partition spaces may also be automatically monitored, by a water levelling system, to eliminate the risk of unintentional lowering of the water level due to leakage, evaporation or the like, and resulting deteriorated radiation shielding protection.
  • the partition elements in the walls and roof are made of sheets of steel applied on a system of steel beams.
  • an additive preferably is added to the water.
  • the partition elements it would be possible to make the partition elements of other materials, such as for example concrete, possible in combination with plastic film to ensure impermeability to water.
  • three of four walls and the roof include waterfilled spaces.
  • the wall between the treatment room and the operator room does however not include a waterfilled space, since the radiation from the radiation surgery equipment, for which the building is adapted, is low in the area behind the equipment and therefore the necessary radiation shielding can be achieved by a comparatively thin layer of steel sheets.
  • the floor is provided with a waterfilled space since the building is adapted to be placed on a foundation in form of a concrete slab which will provide for the necessary radiation shielding.
  • a building according to the invention may be constructed with spaces filled with various materials in all of the boundary elements defining the building.
  • the walls, roof and possibly the floor of the building may have another design.
  • the spaces need not be hermetical closed to prevent evaporation.
  • the inlet as well as the outlet openings need to be of a larger dimension since a pulverous or granular material, as a rule, are not possible to be pumped, but must be poured or blown into and out from the spaces.
  • the outlet openings may, for instance, be in form of lids in the bottom portions of the walls to allow emptying.
  • connection joints between different units When assembling the building of two or more building units, it is important that all connection joints between different units will be performed in a sealed manner to prevent radiation from escaping to the environment. This is suitably ensured by forming all connection joints in a labyrinth form.
  • the building structure is preferably constructed at an industry plant and in the preferred embodiment the building is assembled by three separate building units. Two units forming the radiation shielded treatment room and one unit forming a non-shielded operator room. Though preferred, but not necessary, all units are assembled at the industry and are provided with electrical system, communication system, temperature control system, ventilating system, as well as inner and outer covering of the walls, roof and floor including insulation if any. However, as an alternative, some of the installation may be performed at the operating site if that is desired.
  • the building thereafter is disassembled at the constructing site, into the separate units and transported to the operating site where they are assembled on the foundation. Finally the radiation equipment, computers and the like, are installed after which the building and the equipment is ready to be taken into operation.
  • a radiation shielded building adapted for use in radiation surgery of human beings is described.
  • the building according to the invention is applicable for any kind of radiation equipment, e.g. equipment for treatment of animals or foods or any other type of living organism or nonliving material.
  • FIG. 1 is a perspective view of a building adapted for radiation treatment, including building units according to the invention
  • FIG. 2 is a cross sectional plan view from above of the building in FIG. 1, and
  • FIG. 3 is a cross sectional side view along the line III-III in FIG. 2.
  • FIG. 1 A treatment room 3 is jointly formed by the building units 1 , 1 ′ and an operator room 4 is formed by the building unit 2 .
  • the building units 1 , 1 ′, 2 has each, in the preferred embodiment, a length in the order of about 6-9 m, a width of about 3-4 m and a height of about 4-5 m. Dimensions that makes them well suited for transportation on roads or railways as well as by sea.
  • the building units 1 , 1 ′ are essentially identical but reversed and include wall portions on three of their four sides, a floor and a roof portion.
  • the fourth side of each of the building units is open in order to mutually define a comparatively large treatment room 3 when placed adjacent each other.
  • a radiation generating unit 5 for radiation surgery is placed in the treatment room 3 as shown in FIG. 2 and 3 .
  • the treatment room 3 has to be provided with a radiation shielding to prevent radiation from escaping from the treatment room to the environment and to the operator room 4 .
  • the radiation shielding for three of the wall portions 6 which are faced toward the outside, and for the roof portion 7 of the treatment room, is accomplished by each having a double walled structure with an inner partition element 8 , an outer partition element 9 and a space 10 forming a closed tank between the inner and outer partition elements 8 , 9 .
  • the partition elements are formed of steel plates or sheets on a system of steel beams, with a space of about 800 to 1400 mm between the plates.
  • the tank 10 may be unitary and common for a whole building unit 1 , 1 ′, but it may also be subdivided into smaller tanks. However, the tanks are separate for each of the building units 1 , 1 ′. Each tank forms a closed, liquid tight container for water which is fillable through not shown inlet openings.
  • the radiation shielding in the intermediate wall 11 between the treatment room 3 and the operator room 4 is provided by a sandwich wall structure including steel plates on a system of steel beams. Between the treatment room 3 and the operator room 4 is also a door 12 which is made of lead to give sufficient radiation shielding.
  • the floor portion 13 of the building unit 1 , 1 ′ is in form of a steel plate and does not in itself have sufficient radiation shielding capacity. However, the floor portion 13 is adapted to interact with a not shown foundation to provide the required radiation shielding.
  • the wall and roof portions 6 , 7 of the building units include inner and outer insulation layers as well as inner and outer covering layers.
  • the building unit 2 also include a recess or accommodation 16 adapted for installation of e.g. ventilation and temperature controlling equipment.
