Cat litter produced by AROPET Co., Ltd. All 39 productshave been summarized in one table for radon measurement results. All products were well below the indoor radon recommended level of 4.0 pCi/L, and the average for the 39 products was 0.419 pCi/L (about 10.5% of the recommended level), with a minimum of 0.289 pCi/L and a maximum of 1.009 pCi/L. Even compared to the typical indoor radon concentration of 1.3 pCi/L, all products had lower levels.

Understand the units first
The report shows pCi/kg·hr (or Bq/kg·hr)indicates the amount of radon released from 1 kilogram of the sample over 1 hour. Emission rate Unit. On the other hand, when assessing human risk, pCi/Lit is expressed in terms of radon concentration per liter of air, which is a different concept.
So on the test report, apart from the emission rate, “Increase in indoor air radon concentration caused by 10 kg of the same material”is calculated. The pCi/L values in the table below are exactly this figure, and they serve as a reference for judging safety in actual usage environments.
- Recommended indoor radon concentration: 4.0 pCi/L (= 148 bq/㎥)
- Typical indoor air radon concentration: 1.3 pCi/L
- Unit conversion: 1 pCi/L = 37 bq/㎥
