Unformatted text preview: Should Engineers Be Licensed Like Doctors? Doctors? Medical Physicist Medical “Medical Physicist “Some people do nuclear Some medicine, others do diagnostic radiology (CT, x-rays, magnetic resonance), others do radiation protection, and other (like me) do radiation therapy physics (for cancer treatment).” (Gonzalez, J. Sept. 10th, 2003) (Gonzalez, Radiation Therapy Radiation “Among other things, I Among have to calculate if the amount of radiation it was delivering was in agreement with measured data.” measured “An incorrectly calibrated An machine may cause serious side effects, including death.” including Radiation Therapy Radiation For this machines, we have a series of For daily checks, weekly checks, monthly and yearly checks. For the daily checks, you could be a technician or a dosimetrist. For the weekly checks, you could be a dosimtrists or a physicist with training in using the equipment. For the monthly checks, you must be a medical physicist. The certification usually depends on national regulations. For example, in the US, to be a certified Medical Physicist you must have a masters degree and 2 years of experience working with a senior medical physicist. Then you have to pass board exams. board Prostate Seed Implants In my case, we also do treatment In planning, dose calculation, dose verification, Brach therapy for cervix, cancer treatment simulation and maybe one or two other things. maybe Brachytherapy is a treatment modality Brachytherapy on which we place radioactive isotopes very close to the target tissue. There are prostate implants, for example, or cesium capsules that are placed inside the vaginal cavity to treat some forms of vaginal and uterine cancer. In Panama we use cesium and we got a new machine called a High Dose Rate machine that works with Iridium. works Death vs. Disaster Death Direct Effect on Direct Human Life Human Responsibility Individual Life Lives of many Example Example 2003 Blackout DISASTER DISASTER On August 24th 1992, Hurricane Andrew struck an On unprepared South Florida and demolished entire neighborhoods.
