Indoor shooting range

Indoor shooting range (1) comprising an interior space (3) for firing ammunition, said indoor shooting range (1) comprising:

• an air ventilation system (5) arranged for providing said interior (3) space with a laminar flow of fresh air (7);
• a detector unit (9) arranged for detecting a concentration of metallic elements, in air in said interior space (3), originating from ammunition fired in said interior space (3) of said indoor shooting range (1), wherein said detector unit is arranged for detecting the concentration of at least one of lead, copper, aluminium, antimony, zinc, tin, manganese, bismuth, iron and nickel elements;
• a control unit (11), communicatively coupled to said air ventilation system (5) and said detector unit (9), for controlling said air ventilation system (5) taking into account a detected concentration, by said detector unit (9), of metallic elements originating from said ammunition fired in said interior space (3) for maintaining said concentration of said metallic elements in said interior space (3) below a predetermined value, wherein predetermined concentration values of metallic elements for the interior space (3) for firing ammunition are stored on the control unit;
• and
• an air sampling system (21, 23, 25), communicatively coupled to said detector unit (9) and said control unit (11), arranged for sampling air at predetermined locations in said interior space (3).
