Radiation Exposure ,Radiation safety- Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video demonstrates how radiation affects the body, the different types of radiology procedures, and safety recommendations.

X-rays ionize human tissue and deposit energy that can cause harmful changes within the body (break the DNA chain). There is a cancer risk from X-rays. The dose of radiation is cumulative. X-rays are considered for carcinogen list. The government is attempting to avoid the use of unnecessary CT scans and x-rays to avoid unnecessary exposure to radiation. This highlights the cancer risk. Doctors need to pay close attention to the risks involved with the use of x-rays. The cancer risk associated with radiation exposure is documented in cases of atomic bomb survivors. The risk for medical uses is controversial and usually played down by physicians. Radiation at a high level is carcinogenic. The level of radiation from x-ray exposure is low. The effects of low-level radiation is not known.
What is the safe radiation level? The safe level is not known. It is known that CT scans, fluoroscopy, mammography and x-rays expose the public to high levels of radiation especially in young females. The risk of exposure should balance the medical benefit. Optimize radiation doses by exposing the patient only to enough radiation to get a clear image. There is a growing concern about the risk associated with giving patient large doses of radiation. The use of CT scans has increased recently in adults and children possibly exposing the patient to an unnecessarily high dose of radiation. CT scan is the method often used to diagnose cancer, diseases fractures and it exposes the patient to a much larger does of radiation than x-rays. Radiation from CT scan of the pelvis equals the same amount as 100 chest x-rays. Children are ten times more sensitive to radiation than adults. 3-4 million children receive CT scans and about 1,500 of them will develop cancer two decades later. Children should not be given an adult dose of radiation.
Radiation dose limits:
CT scan of the pelvis has the highest level of exposure to the skin, marrow and gonads. Use mini fluoroscopy C-arm whenever possible. Fluoroscopy emits a lot of radiation. The closer the extremity is to the radiation source, the higher the dose of radiation the patient receives. When the distance from the beam increases, the dose of radiation is less. Attempt to decrease exposure time. Radiation intensity follows the inverse square law. It is all about distance. If the intensity of radiation at 1 meter from the source is 100 mR/hr then the intensity of radiation at 2 meters from the source is ¼ or 25 mR/hr in same unit area. At 3 meters from the source, the intensity of radiation is 1/9 the original or 11.1 mR/hr.
Units of radiation (radiation nomenclature)
•Roentgen: unit of radiation exposure in air.
•Rad: energy absorbed per gram of tissue.
•Rem: biological effect of a rad.
There is less exposure to the physician when imaging a smaller body part. Larger body parts create an increased exposure to the physician when imaging a patient with C-arm. Do not be in the direct path of the radiation beam.
Protection:
•Monitoring: a dosimeter badge only records how much radiation you have received. It does not protect you from exposure to radiation.
•Shielding: lead gowns and aprons work to stop exposure to fluoroscopy radiation. Lead aprons attenuate scattered radiation by about 95%.
•Position
Rapidly dividing cells are most sensitive to radiation exposure: sperms, lymphocytes, small intestine, and stomach. Radiation damage seldom appears at the time of radiation. The first effects of radiation damage is usually seen as a drop in the white blood cell count. The first external sign of damage is seen as a skin burn. Studies suggest that people who use fluoroscopy extensively have a higher rate of cataracts.
Early effects or radiation exposure:
•Death
•Hematological depression
•Chromosome aberration
•Skin erythema
•Epilation.
Team exposure to radiation
•Direct beam 4,000 mrem/min
•Surgeon (1 ft.): 20 mrem/min whole body
•First assist (2 ft.): 6 mrem/min whole body
•No exposure (5 ft.) at scrub or anesthesiologist.
•6 feet is safe.

This is really great information and I wish more doctors, dentists, etc were aware of it. I am working on a proposal now for medical practitioners to provide them with resources to protect themselves and patients for this exposure. If only I could find someone who would listen! Thanks for sharing this

[henocasf]

this has helped me understand about how much radiation I took in when I hiked into chernobyl

[albertking]

Thank you for sharing this is my new job and they never told me about the cancer risk.

[klakson]

the fact is, every dose of radiation damages the cells and thus increases probability of cancer later in life - even background radiation for that matter
it's more of a calculated risk in case of x-rays

Hi, I had about 40 RTG in one year, with CT, MRT ( most one leg, back, all body)I really affraid what can happend to me later. No one says about it, no one gives answers, there is no subject. I ll try to look at my blood and care about myself in future. Thank You for Your job.

[ciscookiethatsgoodenough]

2 hospitals xrayed me and ct'd me extensively. All refused apron use, and insisted the science of it was not relevant anymore, and in fact in error. I smelled burning flesh when I got the first bunch of xrays done. Since that first experience, (then the others followed in same two weeks but i believe the first one was at a much higher dose than maybe I should have received?), my heart and chest currently hurt and feel singed.I'm a meditator, so I know the difference.Also though, respect and thanks to doctors who are overwhelmed with trying to care for us. It is not their fault.

Can a head xray to a 7 year old cause a brain tumor? Are the radiology department mandated to keep records of the radiation dose used on the patients during the xray?

[wesdale]

My blood test came in and my doctor told me my cholesterol is high.
But, because of that, l must check your prostate, it might also cause
She referred to a Urologist to check my prostate 😂
He in turn sent me for a bone scan. There the nurse injected with something that has no side effect according to her.
After a 2 1/2 hr wait, she put me under an X Ray machine for ONE HOUR, you get the picture.
Since then l have been more sick, disoriented, chest pain, pain in the prostate area, things that l never had all my life.
This is to tell you how doctors abuse the Medicare system

[MrTortureandtorment]

Extremely informative video. Patients should be concerned when ordered to have an X-Ray.

[izzygee]

Great video sir! Thank you so much for creating it. 🙏🏽

I wonder if I’m being a hypochondriac but I seriously am so mad at myself for being so stupid. I broke my pinky finger, the base of my proximal phalanx about a year and a half ago, and unfortunately it healed with a malunion, I should’ve just let it go, but I’m a guitar player and I was considering doing osteotomy for it. It still affects me everyday because it healed with a hyperextension and rotation at the base of the proximal phalanx. Which is the worst place to break your finger cause it’s right by the joint. I wish I would’ve had surgery but for whatever reason the one I went told me to just buddy tape it conservatively. I didn’t get a cast or splint. Not even advice on best position to keep it in. I went to several different surgeons since then and got probably maybe 7 to 8 different x-rays over the course of the year, I also got a CT scan recently on my hand as well, I have been reading a lot about how I can damage the DNA, I can’t really explain it, but before my hand felt stupid and now it feels retarded. I feel like my hand is so weak, I just tried playing the guitar and maybe it’s partly muscle memory but I feel like I basically nuked my hand and destroyed it. My hand CT was a high 4.18 mGy and 101 DLP. That’s over a year and half of background radiation blasted into my hand. I also got a MRI to even though they said that’s non ionizing. But I’m sure there is still risk. Which is according to research about a year and a half background radiation. The problem is they don’t tell crap about that as you’re going into appointment. Wish they did. Cause I read it can damage your dna and it’s not like after a year and a half it’s back to good. It stays with you forever. This is the most covered up conspiracy of our generation. Withholding the risks of radiation ☢️ in our lives

[marjoriesell]

I had an hour of X-Rays on my back, hips and legs. The tech had to repeat many times because the machine needed to be replaced and wouldn't stay in place. I feel my skin is warm. Would a checkup be needed to see if I'm OK?

[AestheticallyViolet]

Bro what the fuck I have had so many CT scans and x rays before…

[canadianbacon]

I dont understand why we dont just stop doing ct scans and start prescribing mris since they give no ionziing radiation? from what ive read MRI gives better images all around?

[pighedshanks]

I was recently been transferred to a process in my work that uses xray machine? Is it dangerous for me? 😔

[serangel]

I think I have had one too many xrays with my last 18 dental xrays I have had many xrays since last summer. I had a mammogram in 2015 It was the hottest summer on record I was in bed for almost 5 days I got a horrible sick stomach worse bone pain in my spine, and I felt like my inards were cooking. I tossed and turned at night and I could not get out of bed from extreme mental and physical chronic fatigue during the day.I have had bad back and bone pain, intestinal and stomach cramps after dental xrays in the first 48 hours too. I kept my eyes open on one dental xray and my eyes started hurting from the direct xray beam going into my retna. I think I am super sensitive or maybe allergic to unatural man made radiation.

[LyndaCrowther-pu]

Thank you for the video. I have made my decision not to have the 4th xray on my fractured humerous. And also no more CT scans on my pelvis which i have been advised to have every 6mths for 5yrrs. As I refused a wider local excision on my thigh area where i had melanoma! I will use sight & touch for possible swollen lympth nodes from now on. 90% chance melanoma won't return.I am 60 next week & scared of radiation poisoning big time!

[nalianna]

After a CT scan I had a few days ago, I have been feeling pressure, and now pain in my head, especially the in the back of the right side of my head. There is so much pressure that it is causing my ear to feel blocked. My insides feel like they are heated especially my chest and my stomach. My skin is beginning to feel tight and I am beginning to feel burning sensations on my back, arms, and neck. I also feel a bit queasy now as well. If anyone has any idea on how to detox from radiation and CT contrast, I would very, very, VERY much appreciate the info.

[taraarrington]

What do you think about the people that are working with and operating directed energy weapons do you think they have a high chance for cancer and radiation risk?

[softie]

Shame on my parents how they allowed my doctor to do my x rays
