What does watt per kilogram (W/kg) represent in radiation measurements?

Watt per kilogram indicates the rate of power absorbed or emitted per unit mass, used to assess energy deposition rates in radiation contexts.

Is the conversion between W/kg and J·kg⁻¹·s⁻¹ complex?

No, converting watt per kilogram to joule per kilogram per second is straightforward with a direct 1:1 ratio.

Why is this conversion important in medical radiotherapy?

It allows accurate specification and control of the dose rate applied to tissues, ensuring safety and treatment effectiveness.
