If the mass of the body is 80 kg who receives a lethal whole body equivalent dose of 400 Gy. Then how much is absorbed.
Correct answer: D. 32kJ
- A. 30kJ
- B. 48kJ
- C. 35kJ
- D. 32kJ
Explanation
correct. Here's the correct calculation:Understanding Gray (Gy):1 Gray (Gy) is defined as 1 joule (J) of energy absorbed per kilogram (kg) of mass.Calculating Total Absorbed Energy:Absorbed energy (J) = mass (kg) × dose (Gy)Absorbed energy = 80 kg × 400 Gy = 32000 J
