# Detriment

A concept used to quantify the harmful stochastic effects of low-level radiation exposure to the human population. It is determined from lifetime risk of cancer for a set of tissues and organs taking into account their severity in terms of lethality, quality of life, and years of life lost. It also considers heritable effects. Radiation detriment is estimated as a sex- and age-averaged risk indicator for a composite reference population.

### from ICRP Publication 135, 2017

The total harm to health experienced by an exposed group and their descendants as a result of the group’s exposure to a radiation source. Detriment is a multi-dimensional concept. Its principal components are stochastic quantities: probability of attributable fatal cancer weighted probability of attributable non-fatal cancer weighted probability of severe heritable eﬀects and potential years of life lost if the harm occurs.

### from ICRP Publication 127, 2014

The total harm to health experienced by an exposed group and its descendants as a result of the group’s exposure to a radiation source. Detriment is a multi- dimensional concept. Its principal components are the stochastic quantities: probability of attributable fatal cancer weighted probability of attributable non-fatal cancer weighted probability of severe heritable eﬀects and length of life lost if the harm occurs.

### from ICRP Publication 126, 2014

Detriment is an ICRP concept. It reﬂects the total harm to health experienced by an exposed group and its descendants as a result of the group’s exposure to a radiation source. Detriment is a multidimensional concept. Its principal components are the stochastic quantities: probability of attributable fatal cancer; weighted probability of attributable non-fatal cancer; weighted probability of severe heritable eﬀects; and length of life lost if the harm occurs.
