RADT 101 Radiation Safety and Protective Devices

[@jessiehenrycastillo4438]

I'm going to take the Radiologic Technology Licensure Exam this December. This is very helpful

[@sjhshah1542]

excellent work and information about this critical topic

[@shahidekbal._.]

You should do more videos. That was So helpful. Thanks.

[@emiliasalas9846]

Excellent video.

[@mouhamadhammami6617]

As a physicist, there are some minor errors in the information given about photoelectric effect, also the Compton scattering wasn't taught correctly. I highly recommend reading more about it. Appreciate the effort!

[@mohamedshabib9686]

is there a link to download the powerpoint?

[@radtvlogs3433]

Good lecture

[@tatianagesundheit9211]

Very niceeasy to understandclear and concise

[@khwezimaphumulo7803]

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!"

[@environmentharikumars7499]

Wavelength, low and high frequency? Thanks for all

[@ratchgaming1484]

Alright 👍

[@wesentolera3658]

Wow how easy understandeble thank you

[@rahulgokhroo6686]

nice video

Grids DO increase patient dose.

[@khwezimaphumulo7803]

@DEAD BABY EATER this increases that patient skin dose due to the introduction of low energy x-rays from interaction with the grid.

IS THIS THE COURSE TO BECOME RADIATION PROTECTION OFFICER?

[@gravedadzero5868]

Yes, russians we are!

[@manjinderdhanoa6237]

TLd should wear inside the lead apron not outside Because we got radiation under lead apron Pl correct it

[@japrilcuadra11]

That's for pregnant woman.

[@Iwillfightcauseigotnothing]

No. If a woman is pregnant, she will wear one inside at the waist level for the baby-and a 2nd one outside at collar level for her. An occupational worker will wear one outside because the apron does not cover the whole body, ur eyes/exterminates/other stuff are also affected and if u only wore it inside they won’t be taken into consideration. On top of that, the lead apron does a very good job at sucking the photons so a false measurement will appear.

@@Iwillfightcauseigotnothing If a woman is pregnant she should not be in radiology taking radiographs at all unless she can do hands free outside the room.

[@asradiologictechnologyasrt7159]

This is not true according to all the books that teach radiology. I agree with you that we should measure what we receive under the apron as that is what is hitting our organs, but that is not correct. Do not miss this on the ARRT! They want to know what you were exposed to as the lead does not cover your whole body so they error on the side of max dose. I like your thinking and agree with you, although it is not correct.

[@manjinderdhanoa6237]

@@asradiologictechnologyasrt7159 whole body dose will be estimated at chest level and lead apron will not stop primary radiation this is only for scatter radiation

[@rahulgokhroo6686]

Grids do not increase patient dose. Slide needs to be corrected.

[@asradiologictechnologyasrt7159]

I agree with you! Grids don't increase the patient dose, but if you do not increase your mAs your image will be too light (quantum mottle) and you will need to repeat it. You have to increase mAs to compensate for the grid. We use the grid conversion factor for this increase.. Please note, mAs is dose, therefore you increase the patient's dose due to mAs increases

[@kristykoster3367]

There are too many mistakes in this presentation. She's just reading the slides and not explaining things correctly. The photoelectric effect ejects an inner shell electron. The "shell" doesn't fill this vacancy, an ELECTRON from a higher energy shell (such as L) does. This leaves a vacancy in the L-shell, so an electron from the M shell fills it, and so on. Each time an electron moves from a higher energy state to lower, the difference in these energy states is released as a photon. This is the characteristic cascade. Also, she mis-read the slide about grids, which DO increase patient dose since they require an increase in mAs.
