Which of the following units is equal to 3.7 × 10⁴ dps?

Question

Quizplus · Accepted Answer

The given value is in units of "dps" which stands for "disintegrations per second". This unit is commonly used in nuclear physics to measure the rate at which a radioactive substance undergoes nuclear decay.

The other options are also units of radioactivity, but they are not equivalent to "dps".

A) 1 Ci (Curie) is equal to 3.7 × 10^10 disintegrations per second, which is much larger than the given value. 
B) 1 mCi (millicurie) is equal to 3.7 × 10^7 disintegrations per second, which is still much larger than the given value. 
C) 1 Bq (Becquerel) is equal to 1 disintegration per second, which is much smaller than the given value.

Therefore, the best choice is D) 1 µCi (microcurie), which is equal to 3.7 × 10^4 disintegrations per second, and is closest to the given value.
