The energy of ionizing radiation transferred to a body weighing 50kg is 12J.

The energy of ionizing radiation transferred to a body weighing 50kg is 12J. Determine the time of exposure to ionizing radiation if its power is 0.02 Gy / s.

Initial data: W (energy of ionizing radiation) = 12 J; m (body weight affected by ionizing radiation) = 50 kg; P (radiation dose rate) = 0.02 Gy / s.

The time of exposure to the body of ionizing radiation is determined by the formula: P = D / t = W / (m * t), whence t = W / (P * m).

Let’s make a calculation: t = 12 / (0.02 * 50) = 12 s.

Answer: The exposure time to ionizing radiation was 12 seconds.
