Safety of Cardiolite (Technetium Tc99m Sestamibi)

I was slated to take a "nuclear stress test" with cardiolite (Technetium Tc99m Sestamibi) but grew concerned when they recommened not holding a small child for 24 hours.  I wonder (a) whether this substance can affect males who are trying to father a child (i.e., any relationship to birth defects, etc.) and (b) are there any risks of being near a small child after the test (i..e, can I go near my 1 year old son)?  Thanks!

Dear Mewshaw,

The overall radiation exposure is relatively low. It is theoretically possible for this to affect a male trying to father a child, but again the risk is low. I would recommend avoiding close contact with your 1 year old for the recommended period of time. It may be a good idea to review with your doctor the indications for the stress test and/or consider a stress test using echocardiography which would avoid radiation completely.

Thanks for your question,
