    This is just great, very well put together. The speed is actually perfect when watching this as a refresher.

    Fantastic! thanks for doing these!

    Sir very nice explanation. You are using which book as ref? What is the ref for the above video?

    Is there any equation that predicts this behaviour for a given energy and material?

    Thank you very much for the useful videos. I think that there is a small mistake at about 10:50. The Rp = energy x 5 (and not energy divided by two)

      Hiya, thanks for the input, can you please link me a reference for that one?

      One is in mm and one is in cm. They are otherwise equivalent.

    thanks extremely helpful. missing new lecture for a while though

    It can be very good if it was slower. It's so fast that it's difficult to follow

    • @roscribbles4155
      @roscribbles4155  8 ปีที่แล้ว

      That's understandable, would it be more helpful if I uploaded at 0.75 speed? I've been meaning to do that for a while.

    amazing stuff. Very well put. But because these are basics and hence need to reach everyone who is new to Radiation Physics. So it would be great if you can slow down your speed considerably. Thanks

    Can you please slow down your speech, or the speed of your videos. You speak way too fast, and its so hard to catch up. What i end up doing is download the videos, and play it in a player at a reduced speed. Your lectures are good. Thanks for uploading. But its more for a person who already knows the concepts and for whom speed won't be a concern. Thanks again!!

      +Med Phy You make a very good point, TH-cam's 0.5x playback isn't really an ideal solution.
      I'll upload some 0.75 speed vids this week.

    Skip due not clear audio

    Thank you very much for aploading, this is indeed very helpful, I have a question though; do you have any video where you explain how to treat irregular/ non-square fields using electron beam therapy technique, using the idea of equivalent square??

    • @roscribbles4155
      @roscribbles4155  8 ปีที่แล้ว

      No worries! I don't actually, but I remember there being a decent section on this in Khan's textbook somewhere, do you have access to that?

  • @antropomorfox9784

    Hi! The increase of Rp (practical range) is due to the contribution of high scatter angle electrons which do NOT pass through as much medium.

    I thought the video was in 1,5 speed for at least 5 minutes. haha
