Lead lineing Sheet Rock

[pengawaresux]

Id love to see how this crew completes a x-ray room, kinda interesting to see how a 3/8" disk is installed over a drywall screw, You are the only person brave enough to post such a video. Post more this is great.

[RHEAD100]

@pengawaresux Nothing Brave about it. I just know what I am doing. By thw way , covering the screws with 3/8 ths inch caps has been elimanated by the Usa building standerds for rdiology rooms.

[pengawaresux]

@RHEAD100 the ncrp report #147 eliminates the use of the disk. the IRPA report 10 course EO-6 states that the twits trying to hammer these 3/8 Pb disks in place were only ripping the lead causing a bigger penetration than the screw made. the NCRP report 147 has made a huge error, the ncrp report 49 & 147 both state that steel has to be 8 times the thickness of the lead, a 1/8" shank does not shield any of the scatter radiation or direct primary beam locations ie wall bucky or cross table work.

this is good to know. US citizens could use this in their homes against the vans with the Xray machines.

God i love mexican workers they rock !

[lovingmusicdotorg]

dont take it off bro. . . everyone i asked said they liked it,

[RHEAD100]

@lovingmusicdotorg THANK  YOU

Shouldn't they be wearing gloves, or something, when handling lead for an extended period? It is a pretty neat process, though. I'm glad that you made the video to share.

[RHEAD100]

If this were an every day thing we would be concerned about safety and take more precaution than just gloves. however we do this maybe once or twice every 5 or 6 years.

It is white lead oxide that is dangerous not the clean gray lead we use.

Thanks for watching.

[brianwesley28]

That's cool. I am glad that you made this video. Any chance of making any future videos of the installation process, if ever contracted for another similar job? That would be pretty cool to see. Thanks, again.

[RHEAD100]

For you ? YES.

The next time we do an X-Ray room I will make a video of the actual intallation and even show how we handle pinatrations like electrical outlets.

[pengawaresux]

@RHEAD100 these guys working with lead in there street clothes then go home to there kids doesnt bother you? do you understand the hazards of Pb? are you serious??? Did you at least warn your workers that by mixing there clothes with a kids clothes will transfer lead to there clothes? Has anyone tested your handy work? can you post the guy that passed your installation? thanks

[datzfast]

actually its the same lead found in fishing weights in wiitch millions of pounds are lost to rivers and water resivours each year, so you see your concerns are unfounded. now you woulnt want to cook in a lead pan or drink water if your pipes were made of it. but its going into walls where people will work their entire carriers so its not that toxic .

[gggunit99]

what type of glue are you using? How did you hang the the sheet rock? If you screwed though the sheet rock and lead sheet did you patch over the screw heads with lead? Good vid!

[RHEAD100]

We used F.R.P. Glue , Water based. Non toxic, no odor, and cleans up with water. When dry , nothing will desolve it. Not even water,

We do use screws. And yes; we do cover the heads of the screws with small lead buttons about 3/8 inch diamiter.

Even the window frames are lined with lead on the inside, and the special X-ray lead glass in the windows is about $150.00 a squair foot.Even the door frames and doors are lined with lead.

[pengawaresux]

@RHEAD100 wow, looks like you used the wrong adhesive.. the glue you used is not ment for metal, check it out here:hXXp://wXw.titebond.com/P­roductLineTB.asp?prodline=34&p­rodcat=4

I bet you used the same glue toback shield the electrical boxes, now that they have fallen off and the staff are getting daily unsafe doses of radiation which does cause cance must make you feel good.. The contractor that hired you should be sued and whom ever if anyone that inspected your work should be sued aswell.

[RHEAD100]

@pengawaresux Are you one of those people that read what you want instead of the actual words. I checked out thise web site. and nowhere did it say it was not to be used on metal. Howewver it DID say that it was very good for plywood gypsum , and git this CONCRET. the electric box covers are soulderd with lead based soulder not glued. My question is "how many X- Ray rooms have you built ????

[pengawaresux]

@RHEAD100 nope I read that the glue you used is not ment for metal, if you would of spent 20 dollars more per pail you would not have the lead slumping causing huge radiation leaks to the staff. You soldered the boxes to the lead sheets? LoL no shit? now thats not brave its stupid and breaks all are quality saftey codes for health care facilities. You say "it DID say that it was very good for plywood gypsum , and git this CONCRET" lol what does concrete have to do with Pb to drywall?

[RHEAD100]

@pengawaresux ha ha ha ha ha ha I went to your you-tube web site and read what you had to say on other peoples videos. W O W !!!!!! you are one of those HECKLERS. Have no idea what you are talking about BUT THINK you do. X-Rays Don't bounce. Google it. I tell you AGAIN I know what I am doing.

Therefore I have no fear. W H A T IS your fear been reading a lot of B/S  I think.

[pengawaresux]

@RHEAD100 ionizing radiation as a rule will not diffuse or deflect, I dont have to google anything on radiation prrotection, but it sure appears as if you have no clue and or code books on how to do as you call "a lead job" now do you? If you call providing facts on how clueless you are when it comes to "lead jobs" well then damn it you caught me heckling

[jeffery19677]

Good thing you are working in Mexico where there are no safety standards. OSHA would use this video against you and fine the sh*+ out of you if you were in the states.

[scflyer55]

Pretty interesting subject- apart from your others RHEAD100 !!

Hey- Thank you for the Milkovic link!

I intend to look into that very closely.

[jewishcrimenetwork]

I have been told that lead is an amazing sound insulator.

[bogdy72000]

quite cool video (: but you should instruct people to wear gloves and masks because lead is highly toxic

[RHEAD100]

Thank you for your comment. You are correct and I will see to it in the future that they do wear gloves and masks.

[boxa888]

yea this is a great video, i always thought of like massive 1 foot blocks surrounding an xray room. 13,000 bucks ! wow! i would love to have an xray shielding room some day for my research. i would like to do tests and see if i could cure cancer, i read that certain people posses powerful cancer resistance and the immunity can be transfered by a blood transfusion, but i would love to try this for myself!

[WarzSchoolchild]

Don't you dare remove this video RHEAD100! Ineresting?... It's FASCINATING! and highly educational. MERRY CHRISTMAS to all those Eager-Beavers!

Check with Goodfellow Metals & Materials for Research & Industry,

Just mention "Lead Helium Balloon"...I set this question in a Cambridge University Exam, to catch out shallow thinkers. "Would a spherical Lead Balloon Envelope fabricated from standard 4lb/sq.ft lead sheet get off the ground, if filled with Helium gas? what size would it be?"

[gabydewilde]

Must make it out of reinforced concrete in a cube shape. First fill it with helium, heat it, then draw a vacuum.

It must support a large bungalow, a big garden, a lake, the fruit trees, a landing strip and a small airplane.

Solar / wind heated hot air balloons around the edges for navigation.

[WarzSchoolchild]

I missed this post, oops!..You Failed the exam! Volume of sphere is 4/3 Pi r^3 and surface area is 4 Pi r^2. Air's density is 1.29 kilos M^3. Relative density of Helium to Air is 0.138:1 Four pound lead is 20 kilos per sq. meter. 108 Meters Diameter is the correct answer! Volume 659,583 M^3 Weight of Air displaced 850,863 Kilos. Surface Area is 36,643 M^2 Weight of envelope 732,870, Add weight of Helium 117,419 Kilos, is 850,289 Kilos. 574 Kilos of Buoyancy. IT WOULD GO UP!

[gabydewilde]

2 km would be nice, then we can have a big garden and a valley for tourists.

I suggest we use wind energy to compress oxygen and hydrogen into big tanks.

Then can tank water for ballast and sell the gas to the little people down there.

I always wanted to sell air in buckets, not for the money, it's one of those because we can things.

[WarzSchoolchild]

You have a wild immagination Gaby! ...but that is good. You might like to know that many natural gas fields, especially the Russian ones, have over 7% Helium, that is often just vented to outer space. It takes less than half an hour for the Helium to leave our planet!... WHAT A WASTE!... 'Castles in the Air' sounds much more fun. Check out the latest 'Super-Fibre' ,PBO stands for (polybenzoxazole). Twice as strong as Kevlar. We could build an entire City in the air! Good thinking! Happy Easter.
