How many Bq/m^3 correspond to 1 pCi/L?

The conversion from picocuries per liter (pCi/L) to becquerels per cubic meter (Bq/m³) is based on the definitions of the units involved. One picocurie is defined as 2.22 disintegrations per minute, while one becquerel is defined as one disintegration per second.

To convert pCi/L to Bq/m³, it is important to recognize that 1 liter contains 0.001 cubic meters. Therefore, to convert:

1 pCi/L can be expressed in Bq/m³ through these steps:

1. Convert picocuries to disintegrations per second:

1 pCi = 2.22 dpm = 2.22/60 dps ≈ 0.037 Bq.

2. Recognizing that 1 L is 0.001 m³ means that:

1 pCi/L = 0.037 Bq/0.001 m³ = 37 Bq/m³.

Thus, the correct conversion shows that 1 pCi/L is equivalent to 37 Bq/m³, making the choice corresponding to this conversion accurate. This knowledge is essential for professionals involved in radon mitigation because precise
