# A hospital uses the radioactive isotope \(^{18}\text{F}\) as a medical imaging tracer. The isotope undergoes first-order decay with a rate constant of \(6.30 \times 10^{-3}\ \text{min}^{-1}\).

What is the half-life of \(^{18}\text{F}\)?

A hospital uses the radioactive isotope \(^{18}\text{F}\) as a medical imaging tracer. The isotope undergoes first-order decay with a rate constant of \(6.30 \times 10^{-3}\ \text{min}^{-1}\).

What is the half-life of \(^{18}\text{F}\)?

- **A.** \(9.09 \times 10^{-3}\ \text{min}\)
- **B.** \(110\ \text{min}\)
- **C.** \(159\ \text{min}\)
- **D.** \(1100\ \text{min}\)
