Which two main factors influence the length of the latent period?

Latent period is the time between radiation exposure and when effects first become evident. The length of this period is primarily governed by how much energy is deposited in tissue (the total dose) and how quickly that energy is delivered (the dose rate). A larger dose or a higher dose rate causes more rapid cellular damage, which overwhelms the cell’s repair mechanisms and leads to earlier manifestation of effects. If the dose is smaller or delivered more slowly, cells have more opportunity to repair damage before symptoms appear, lengthening the latent period. Factors like patient age, weight, or how often imaging occurs affect overall risk or cumulative exposure, but they don’t set the timing of when effects will show up after a single exposure.
