Backgrounds in Kimballton

 Kimballton (limestone) (Bq/kg) 

40K  18±1, 13±1

226Ra  1.2±0.1, 1.9±0.2

226Th  0.6±0.1, 0.9±0.2

 Radon concentration 

222Rn < 14.8 Bq/m3

Rock Strength: ~150 MPa

 Gran Sasso (Dolomite rock)

(Bq/kg)

40K  15

226Ra  5

226Th  0.3

 Radon concentration 

222Rn  40 – 70 Bq/m3
