How much radiation is in a nuclear stress test?
The total amount of radiation in nuclear stress test is approximately 11 millisieverts in women and 9 in men. In comparison, individuals living at higher elevations eg in denver colorado, would get background radiation of approximately 3 millisieverts/year. A small amount.
