1.2Objectives:
Thisresearchaimstoexploreandevaluatedifferentmethodsforimprovingtheregulationof~(220)Rnconcentration.Thefindingswillcontributetothedevelopmentofmoreefficienttechniquesforreducinghumanexposureandhealthrisksassociatedwiththisradioactivegas.
2.MethodsforConcentrationRegulation:
2.1VentilationSystems:
Ventilationsystemsareeffectiveinreducing~(220)Rnconcentrationsbyincreasingairexchangerates.Properlydesignedandinstalledsystemscanhelpdiluteanddisperseradongas,decreasingitsconcentrationinenclosedspaces.However,theefficiencyofventilationsystemscanbereducedbyoutdoorweatherconditionsandenergycostsassociatedwithincreasedairflow.
2.2SealingTechniques:
Sealingcracksandgapsinbuildingstructurescanprevent~(220)Rnfromenteringindoorspaces.Thismethodhelpstoreducetheoverallsourceofradongasandconsequentlylowersitsconcentration.However,theeffectivenessofthistechniquehighlydependsonthequalityofsealingandmaintenanceofthebuilding,asnewcracksmaydevelopovertime.
