Which metric is used to compare the risk of cancer due to radiation from different types of tissues?

Effective Dose is the correct metric used to compare the risk of cancer due to radiation from different types of tissues. This metric takes into account not only the amount of radiation absorbed by the tissues (absorbed dose) but also the varying sensitivity of different tissues to radiation. By incorporating tissue weighting factors, the effective dose provides a risk-adjusted measure that reflects the potential biological effects of radiation exposure across various organs and tissues, especially considering their diverse responses to radiation.

Utilizing the effective dose allows for a standardized method to assess and compare risks from exposure, which is particularly important in determining safety standards and regulations in medical settings, occupational exposure, and environmental assessments. This makes it a crucial tool in radiation protection and management, as it relates to understanding cancer risk and ensuring that exposure is kept to a minimum. The other metrics, while important in their own right, do not provide the comprehensive assessment of risk across different tissues as effective dose does.
