SUMMARY
The discussion focuses on calculating the number of radioactive atoms in a 6GBq sample of 99mTc and determining its mass. Using the decay constant (λ) derived from the half-life of 6 hours, the number of nuclei (N) is calculated as 5.21 × 1017. The mass of the sample is subsequently computed to be approximately 8.18 × 10-7 kg, utilizing Avogadro's number (6.023 × 1023) and the mass number of 99mTc.
