Abstract

The present invention relates to compositions useful for isolating a portion of a wellbore. In one embodiment, a composition includes a sealant composition containing a wellbore treatment fluid and a set modifier component. The sealant composition can be placed into the wellbore and subjected to ionizing radiation that alters the set modifier component, triggering the setting of the sealant composition.
