Thanku sir ❣️❣️ helping word (re)🤣
Very 👎 bad, na hi clean dhik rha hai na hi clear sound hai 😄.....na hi kuch samaj me aa raha hai .....sir Thora aacha se video 📹 bna e plz ....esa esa to aap ka Sara video...bear hai ,,
sir radiation hazard or protection ke notes kaha se mile ge
Word ko bade me likhiye sir
Sir b X r t 1 years ke liye harzed aur physics and radiography and photography me view ke liye questions batiya na sir 🙏plz
Big fan from nepal ,highly appreciate you🙏🙏🙏
Sir arts ke baad kya ham radiographer ban sakte hai please give me advice🙏🏻🙏🏻
Vary useful.
I need your help
Plz upload all note in English
I want to talk with u
Sir Brt me center ke competition ke liye book suggest kro plz
Hazards not hazzards
Sir MCQs and quations pe lectur lo na...
Nice class sir ji
Tq so much sir

Sir ye sab krvao aap
Re kya hota h
Notes provide kr do sir plzz
Sir bsc radiography ke bad kya kare jisme iscope ho
👌👌👌👌
Sir part 2 please 🙏
Sir next part of this video is found
Kindly also tell about AERB limits which are applicable in our country....these limits are lower than ICRP sugggested limits for occupational worker
Sir please make it's second part ... protection for patients...!!!
Sir please iska 2nd part...protection for patient and environment.....
Hello sir. May i know what app did you use for your lecture online? I am applying for academe tr in bsrt and i am also a newbie in teaching. I'd really appreciate if you u see my comment. Your answer will be a big help to people like me. Thank you sir
Very nice dear sir thanks
Sir if these are the principles of radiation protection ..then what is Distance, time and sheilding
Sir radiation safety regulatory aspects me Kya at A he
Thank you sir 🙏
Bss ,basic safety standards alara m nhi aata sir , alara only for worker,
Part 2.. radiation protection for patients and environment..???😭😭😭😭
Awesome ❤️🙏🏻
Nice lecture👍
Sir Radiation protection for Operator ka role number 5 Kya sirf dental radiology ka leya hai ?
Great video
Vry nicely explained sir...tq
audio is not good sir
Excellent sir
Well Explained...Awesome Sir
nice video
Grids do not increase patient dose. Slide needs to be corrected.
excellent work and information about this critical topic
Excellent video.
IS THIS THE COURSE TO BECOME RADIATION PROTECTION OFFICER?
Good lecture
You should do more videos. That was So helpful. Thanks.
I can imagine a quantum field theorist listening to this presentation and they are like "No!, photon interaction does not kick electrons off their orbitals but causes electron field to blah blah blah quantum entanglement blah blah blah ... quantum field theory!"
is there a link to download the powerpoint?
So many spelling errors in the presentation. Traditional units should not be taught anymore.
TLd should wear inside the lead apron not outside
Because we got radiation under lead apron
Pl correct it
Wavelength, low and high frequency? Thanks for all

Grids DO increase patient dose.
Wow how easy understandeble thank you
Yes, russians we are!
Very niceeasy to understandclear and concise
حبيبنا والله يا دكتور احمد حببت لينا ال NUCLEAR MEDICINE
اخيك كامل حسن
ماشاء الله زشرح مبسط وطريقه مفهومه
جزاك الله خيرا 🥰🥰
يافندم انا ابنى جايب 75%علمى علوم لو سمحت تنصحنى بلمعهد الخاص وﻻ الكليه الخاصه بسزى محضرتك عارف الظروف ارجوك ترد عليه ربنا يجزيك كل خير
هايل ... القناة دي اكتشاف .. كنز
حضرتك بتدرس ءي ؟!
