Uranium is a naturally occurring weakly radioactive element. High levels of uranium in water may increase the risk of cancer and kidney damage. Most of the uranium that is ingested by food or drink by the human body is excreted, but some amounts are absorbed into the bloodstream and kidneys.
Education and Training for Oral Surgeons. To be certified as a diplomate of the American Board of Oral and Maxillofacial Surgery, an oral and maxillofacial surgeon (commonly called an OMFS or oral surgeon) must graduate from an accredited dental school and be licensed in the state in which he/she is practicing.
Oral surgeons have many years of education and training, and are consequently well-paid. According to the BLS, oral and maxillofacial surgeons earned an average wage of $104.06 per hour as of 2012, and an average salary of $216,440 per year -- more than six times as much as the average dental assistant.
