Physics, specifically relating to the physics of radiation and radiotherapy machines

Light is a fundamental feature of our life’s, but when the nature of light is questioned every rational person thinks they know the answer. Even the great mind of Albert Einstein did not know the full answer. He wrote “all...

When people talk about Radiation, they often describe a substance that is scary, dangerous, and not well understood.  This is generally a fair assumption. You can’t see, hear, taste, feel, or smell radiation, yet is large doses it can be...
How are Physics and Radiotherapy Related?   So what does physics have to do with radiotherapy, and for that matter what does physics have to do with medicine? Isn’t physics done at high tech laboratories such as the large hadron...
As much as I would like to think that I am a brilliant writer (I’m not, but I try), somethings are best explained in video. And since I am not  great in making videos- I hope to be one day-...
Early days-Kilo voltage Treatment Machines: Radiotherapy Machines #2   Kilovoltage treatment machines were the workhorses of radiotherapy in the 1920s to 1960s. We owe a lot to these devices for developing the practice of radiotherapy. And now when modern radiotherapists,...
We can’t feel, see, hear, smell, or taste it!   Ionizing Radiation is strange! It’s not like many other things we come into contact in our day to day lives. We can’t hear it, we can’t see it, we can’t...
Before I talk more about some of the other radiotherapy devices used throughout the history of radiotherapy, I want to explain the common ways of producing the radiation. These are basic components needed in any radiation device and are achieved...
“If you have been exposed to any form of radiation, either for medical diagnostic purposes (fluoroscopy/mammography/other medical x-ray exams) or in the course of radiotherapy treatment, or if you are otherwise concerned by excessive radiation exposure, overload or poisoning (such...
If you did not already know background radiation is everywhere! But do we need to worry about it? Background radiation is the radiation that is naturally around you and it’s been there for many millennia. This may be an eye...
Right, let’s step back a bit and talk about what exactly is radiation. Many people are curious about what it is and hopefully after reading this you will realize that it’s not as mysterious as you first thought. I often...
