Nuclear Medicine Technologists – Career Opportunities
Nuclear Medicine Technologists handle medical equipment, administer radiopharmaceuticals to patients, and observe the characteristics and functions of the relevant tissues or organs.
They create diagnostic images using cameras that detect and map the radioactive drug in a patient’s body, and they explain test procedures to patients. The images are interpreted by a physician.

Medical Centers And Hospital Radiation Exposure, Renewed Concerns
Various recently published studies about the relationship between low dose radiation and cancer fanned again the discussion about risk and benefits of modern diagnostic techniques and in particular Computer Tomography (CT). According to an article recently published in IMAGE (Marie H. Meynadier, Vol. 21, no. 10 – March 10, 2008), it is predictable that in a few decades up to 2 percent of cancers in the United States could be linked to the administration of diagnostic x-rays, even if the ability to monitor the increase in cancer related to radiation exposure will be very difficult as radiation-induced cancer can take up to 20 years to develop.
Since many years the relationship between cancer development and radiation exposure has been studied and there are hundreds if not thousands of publications related to this topic. The problem is that a third of all people get cancer anyway, at some time in their lives, and hence it is quite difficult to find evidence that low doses of radiation cause cancers that would not have otherwise occurred. Even for the 80,000 to 90,000 survivors of the atomic bombs exploded over Hiroshima and Nagasaki, exposed to very large radiation doses, it has been hard to find a direct relationship between excess cancer development and radiation exposure. According to Japanese statistics, from the people who were exposed in 1945 (and did not die immediately) nearly half are still alive. A statistically significant increase in cancer was found at relatively high exposure level of 50 millisieverts (mSv is the unit commonly used to measure the effective dose in diagnostic medical procedures), which is about 16 times the current annual average for Americans from medical exams and about 21 times above the average natural background effective dose in the USA. But these numbers need to be analyzed with care. There is a controversy between scientists if levels below 50 mSv can be considered as safe and about the real (and statistically proven) rest-risk of low radiation exposure.
