Tiny amount of radiation- it's actually less radiation than you would get by taking a cross-country plane flight. The bigger question is- why are you getting the scan? There aren't a ton of indications for doing a scan in someone who is pre-menopausal.
BTW- Dental x-rays are a HUGE amount of radiation!
Here's the thing- a T-score should not be looked at in someone who is pre-menopausal. Only a Z-score. (the Z score looks at age-matched normals). So, it sound like someone might have done a less-than-optimal job reading your scan in the first place. Make sure that if you have another one, it's being read by someone who knows what they're doing (preferable someone who is certified in clinical densitometry).
ALSO- I'm not sure why a forearm Dexa was done. These generally are done in people who have had hip replacements or spine surgery and can't have the typical spine/hip scan done. Sometimes they are used in people with hypothyroidism.
Unfortunately, this happens a lot. Inappropriate ordering of an inappropriate test, leading to lots of unecessary stress on the part of the patient.
