Ok, I have been doing some Radon measuring around my house using a brand new Gamma Scout Geiger counter and have found nothing beyond 4 cpm (alpha) this = 0.06 mREM/hr or 0.6 nSv/hr. This is quite low. However on a trip to Campbell River (~ 200miles North of Nanaimo on Vancouver Island) the readings for my basement suite hotel room were over 10x stronger than in Victoria! Ouch !! 0.6mREM 6.0 nSv/hr Going over to Quadra Island of the coast of Campbell river was way more enlightning!! I visited an old Uranium mine site from the mid 1930's and took readings. Unreal the amount of radiation that can come from a natural mineral outcropping !! The readings in air were 2.3 mREM. The readings at 3cm away from the mineral outcopping ( this case it was a mineral known as Carnotite or Potassium Uranium Vanadate) was over 35.7mREM 357mSv/hr on Alpha beta and Gamma combo measurement!!! that's a wee bit dangerous! Anyone done Radon testing before ?
