250 kBq is equivalent to how many µCi?

• A. 5.5 µCi
• B. 6.7 µCi
• C. 7.0 µCi
• D. 8.2 µCi

Answer: (B)

To convert from kilobecquerels (kBq) to microcuries (µCi), it is essential to understand the relationship between these units of radioactivity. One curie (Ci) is defined as 3.7 × 10^10 disintegrations per second, while one becquerel (Bq) is defined as one disintegration per second. Consequently, one microcurie (µCi) is equal to 3.7 × 10^4 Bq. To perform the conversion from kBq to µCi, you can follow these steps: 1. Convert kilobecquerels to becquerels: \[ 250 \, \text{kBq} = 250 \times 10^3 \, \text{Bq} = 250,000 \, \text{Bq} \] 2. Convert becquerels to microcuries: \[ \text{To convert Bq to µCi, use the following conversion factor:} \] \[ \text{1 µCi = 3.7 × 10^4 Bq} \] Therefore: \[

To perform the conversion from kBq to µCi, you can follow these steps:

1. Convert kilobecquerels to becquerels:

[

250 , \text{kBq} = 250 \times 10^3 , \text{Bq} = 250,000 , \text{Bq}

]

2. Convert becquerels to microcuries:

\text{To convert Bq to µCi, use the following conversion factor:}

]

[

\text{1 µCi = 3.7 × 10^4 Bq}

]

Therefore:
