The radiation from a nuclear cardiac stress test, which typically involves the use of technetium-99m or thallium-201, does not stay in the body for an extended period. Here's a breakdown:

Technetium-99m (Tc-99m): This isotope has a half-life of about 6 hours. Most of the radiation is gone within 24 to 48 hours as the body eliminates it primarily through urine.
Thallium-201 (Tl-201): It has a longer half-life of about 73 hours, but the majority of the radiation is still cleared from the body within a few days, with significant amounts gone within 48 hours.

After a few days, only trace amounts remain, and the radiation exposure drops to negligible levels. However, the exact time can vary slightly depending on individual factors like kidney function, since the kidneys play a crucial role in eliminating these substances from the body.

For most people, by one week, the radiation levels are very low. It's worth noting that the radiation dose from these tests is relatively small compared to other medical imaging procedures, and the benefits of the diagnostic information provided are generally considered to outweigh the risks from the radiation exposure.

If you have specific health concerns or are worried about radiation exposure, it would be best to discuss these with your healthcare provider who can provide advice tailored to your health situation.
