    Transcript
    Here we have ionizing radiation. On X-rays i'll have to walk you through what's known as gamma, alpha, beta particles, and why that's important to you. You will do that in a little bit. And another reason that this also become important to us is that even to this day, especially in a day where we are looking for alternative energy there are societies out there that well for whatever reasons promote nuclear energy. The point is this. Because we have pratically speaking nuclear energy out there there is every possibility that accidents occur. In fact, Chernobyl. In fact, the far east the recent explosion with Japan. What does that mean to you. Fifty, sixty years later, these patients are still coming in with a cold nodule in the thyroid. Welcome to papillary cancer of the thyroid. These things never go away. Is that clear. These things will be aroud for a long period of time. It's important that you take a proper history of your patient. Uranium - Lung cancer. Head and Neck radiation - Thyroid cancer. Radium dial watchers - osteosarcoma. I was talking to another patient the other day. It was amazing. And his family came from New England. Came from radium dial watchers. And the way that it worked up in Connecticut is that they took such pride in making their watches, that the way in which that they would then paint their 'dial' on their watch was great pride, with ink that then contained radium. So what do they do? They would then take this, we'll call it a pen, felt tip, or what not and dip it into the radium and lick it. Imagine doing that for 10, 15, 20 years. Imagine doing that for the rest of your life. What are you...
