Radiation-induced triggering for set-on-command sealant compositions

Sealant compositions comprising: a wellbore treatment fluid; a set modifier; and, a polymeric component that inhibits release of the set modifier; wherein exposure to ionizing radiation causes degradation of the polymeric component resulting in release of the set modifier and an increase in the mechanical strength of the sealant composition.
