Final answer:
In risk assessment, assessing hazards involves identifying potential hazards, such as the type of ionizing radiation, energy per event, activity level of radioactive source, and mass of tissue affected.
Step-by-step explanation:
In the second step of a risk assessment, which involves assessing hazards, the goal is to identify potential hazards that could cause harm. This step focusses on creating an inventory of these hazards to understand what you are dealing with.
For example, if a person is exposed to ionizing radiation, you would need to make a list of the known factors. This includes the type of radiation, the energy per event, and the activity level of the radioactive source, as well as understanding the mass of tissue affected by the radiation. These factors are critical inputs for subsequent steps such as calculating the dose received by the individual.
