DESCRIPTION:Speakers: RABECCA RAMOKONE THELEDI (UWC)\nRadon is a naturally
  occurring radioactive inert gas in the decay chain of uranium-238.  High 
 radon levels in houses have been linked to the occurrence of  lung cancer 
 via the deposition of radon progeny in the lungs.\nThe radon activity in h
 ouses depends on the concentration of radium in the soil below the house a
 nd the diffusion of radon into the house. Another pathway is the concentra
 tion of radium in building materials.  There has been concerns that indoor
  radon from granite countertops and zircon tiles might contribute signific
 antly to the radon concentration in a house.  \nThe aim of this work is to
  look at how much radon is coming out of some South African tiles and gran
 ite used in houses\, as well as other building materials.  Radium content 
 has been measured using a NaI detector and radon with the use of a RAD7 co
 ntinuous radon monitor as well as electrets ion chambers. Preliminary meas
 urements will be presented on material that has been used in construction 
 in South Africa.\n\nhttps://events.saip.org.za/event/7/contributions/5269/
