Which measurement indicates a higher level of radon concentration?

• A. 100 pCi/L
• B. 200 Bq/m^3
• C. 4 pCi/L
• D. 150 Bq/m^3

Answer: (A)

To determine which measurement indicates a higher level of radon concentration, it's important to understand the conversion between the two units used: picocuries per liter (pCi/L) and becquerels per cubic meter (Bq/m^3). One picocurie equates to approximately 37 disintegrations per second, while one becquerel reflects one disintegration per second. The conversion between these two units is as follows: 1 pCi/L is equivalent to about 37 Bq/m^3. Using this conversion factor, we can evaluate the concentrations: - Option A has a concentration of 100 pCi/L, which converts to about 3,700 Bq/m^3. - Option B presents 200 Bq/m^3, which remains as is since it's already in this unit. - Option C shows 4 pCi/L, which converts to roughly 148 Bq/m^3. - Option D offers 150 Bq/m^3, again remaining the same. Comparing these values, 100 pCi/L (converted to 3,700 Bq/m^3) is significantly higher than the other concentrations provided. Therefore, this measurement indicates the highest level of radon concentration among the

To determine which measurement indicates a higher level of radon concentration, it's important to understand the conversion between the two units used: picocuries per liter (pCi/L) and becquerels per cubic meter (Bq/m^3).

One picocurie equates to approximately 37 disintegrations per second, while one becquerel reflects one disintegration per second. The conversion between these two units is as follows:

1 pCi/L is equivalent to about 37 Bq/m^3.

Using this conversion factor, we can evaluate the concentrations:

• Option A has a concentration of 100 pCi/L, which converts to about 3,700 Bq/m^3.

• Option B presents 200 Bq/m^3, which remains as is since it's already in this unit.

• Option C shows 4 pCi/L, which converts to roughly 148 Bq/m^3.

• Option D offers 150 Bq/m^3, again remaining the same.

Comparing these values, 100 pCi/L (converted to 3,700 Bq/m^3) is significantly higher than the other concentrations provided. Therefore, this measurement indicates the highest level of radon concentration among the
