One gray=0.01 Rads...Incorrect (very), Correct.....One Gray = 100 Rads.

BI-RADS is a system of categorizing results of mammograms. BI-RADS 2 means that the finding is benign -- not cancer. Such a result would be typical if a lymph node were found in the breast.
BI-RADS 4 on a mammogram means there is a suspicious abnormality, and a biopsy might be required. It does not necessarily mean cancer.
BI-RADS is a scale or system for categorizing mammogram results. Like the Richter scale measures earthquakes, and the Fahrenheit scale measures temperature, BI-RADS is a way of classifying mammogram results so that communication between health care providers is easier.
50 rads per hour is 200 times the maximum safe continuous exposure rate. It depends of course on how long you are exposed to 50 Rads per hour. If you are exposed to 50 Rads per hour for only 15 seconds you will be just fine, where as if you were exposed for 10 hours total during a two week period, you are dead.
