Yes - in principle, but not in a narrow sense ... 



I think the hormetic effect is triggered by the presence of mutagenous agents, and vanishes after the agent is gone - correct.



But: 



First, once the agent is removed, the effect may last for some time ... the repair crew needs some amount of boredom to fall asleep :=)



Second, the presence of one agent (radiation, i.e.) may trigger effects helping against effects of other agents (chemical mutages, i.e.), because there is 

REPAIR, not DEFENSE.
