# In accordance with the philosophy of keeping exposures ALARA | #If a student becomes pregnant, she is encouraged to voluntarily consult with the program director concerning the most appropriate procedure to ensure that exposure to the fetus is less than 500 mrem (5 mSv) for the entire gestation period. In addition to the radiation badge worn on the outside collar, a radiation badge is worn on the front abdomen area under the lead apron. For a student on the fetal monitoring program both badges are exchanged on a monthly basis. | ||
# In accordance with the philosophy of keeping exposures ALARA, the RSO has established levels at which the dosimetry company will provide immediate notification of a higher than normal reading. These notification levels are presently as follows: | |||
