None: Tbere is no radiation exposure on a nuclear cardiology stress test. The tracer chemical is a harmless radioisotope, usually technitium, but sometimes thallium, which is entirely eliminated from the body within 24 hours after it is injected. The radioisotope is simply used as a tracer to assess the blood circulation to the heart muscle regions.
