Characteristic vs Bremsstrahlung Radiation: What's The Difference?

Types of Radiation In Medical Imaging: • Types of Radiation In ...
In this video I talk about Characteristic and Bremsstrahlung Radiation, what they are, their differences and everything in-between.
This is an extension of a previous video I did on different radiation types which has been linked above.

WHO AM I:
I'm Sahand, a Lecturer and Radiographer (and now CZcamsr?) in Sydney AUS. I received my PhD (Medicine and Health) this year in 2023 on breast cancer imaging and radiation dose. I'm a lifelong learner, forever curious about the day to day things, and I'm here to make videos and give you my own unique take on the concepts that you may need some extra help with.

Correction: the Cathode is negative (-ve) and the Anode is positive (+ve)

[@shukriyahussain1717]

You have incredible teaching methodology ,keep up the good work 👏

[@sinead9315]

I'm studying Radiotherapy and could never wrap my head around the difference between the two until this video so thank you so much! Your videos are gonna get me through my exams :)

[@SahandHooshmand]

I agree, it can get quite confusing, glad it was useful

[@ab_khanayy]

best explanation on youtube!

[@AngadSingh-asm]

Very nicely explained and excellent presentation!

[@setayeshabdollahpour3067]

Brilliant teaching🙏🏻✌🏻

[@user-uj5ko8zt6x]

You rescued me Sahand;)

[@dominicestebanrice7460]

I'm not studying medical imagine just interested in electromagnetic radiation and physics in general and have to say, this was a superb presentation.....you're a natural.

[@SahandHooshmand]

Thank you the kind words!

[@hitanshioza6847]

I’m in my Second year of pure science and couldn’t understand this from the textbook. You’ve explained it really really well!

[@SahandHooshmand]

Glad you found it useful my friend

[@der.Schtefan]

You can simply say Bremsstrahlung, without adding the word " radiation". Good pronounciation, btw.
Breaking it down would be easier as Brems (break-)
strahl (ray/radiate)
-ung (-tion)

6:23 I don't understand how electron is getting that much close to nucleus in bremsstrahlung

[@rgravi]

if the electron is negative and the nucleus positive, why does electron decelerate? shouldnt it accelerate since opposite charges attract?

[@SahandHooshmand]

Great question! The electron, being negatively charged, is indeed attracted to the positively charged nucleus due to their opposite charges. In the case of bremsstrahlung (braking) radiation, the electron approaches the nucleus and is deflected due to the attractive electromagnetic force. However, it's not a straightforward acceleration toward the nucleus because the electron doesn’t directly collide with it. Instead, as the electron passes by the nucleus, its path curves due to the attraction, which changes the direction and speed of the electron (i.e. velocity). This deflection leads to a rapid deceleration or reduction in the electron's velocity along its original path/trajectory. In this rapid deceleration, the electron releases energy in the form of X-ray photons, which are known as 'bremsstrahlung radiation'. So, while the electron does 'accelerate' in the sense that it changes direction due to the attractive force, it also loses energy as radiation because of this sudden change in velocity. Hope that helps

@@SahandHooshmand Thank u!

[@shukriyahussain1717]

What is bindinh energy?

[@SahandHooshmand]

It’s the energy required to remove an electron from an atom/nucleus, overcoming the electrostatic force holding it in place.

[@rorovinces3994]

Hi, I sorry but I think your drawer made a mistake and draw Cathode (+) instead of negative 😅

[@SahandHooshmand]

Indeed I did and learnt of it after the fact! I put a pinned comment under the video flagging that when I found out. Apologies for the confusion

[@MadinayKaMusafir]

Can you tutor me?

[@SahandHooshmand]

Sure
