Why is it dangerous to be exposed to X-rays but not or at least much less dangerous to be exposed to radio waves?

X-Rays lie at a different end of the electromagnetic spectrum to radiowaves.

X-Rays are very high frequency and very small wavelength. This means they are very high in energy. As a chemist I can use X-Rays to knock electrons out from low lying orbitals or cleave covalent bonds....both are very dangerous to biological systems (kinda like being shot by tiny bullets, smashing things apart such as DNA and essential proteins).

This also means we get radicals and other reactive species that will undergo unnatural reactions in our bodies (in many cases, they can be oxidising which is very dangerous in the highly reducing environment of our bodies).

If X-Rays are like tiny bullets, radiowaves are like tiny pingpong balls. You get hit by one and it's not a big deal. They will transfer some energy to you....some will pass right through you. But generally do not possess enough energy to do any major harm.

This is a very basic overview. If you want to dig a little deeper, look up 'electromagnetic spectrum' and note how the less harmful things appear on the low-energy (long wavelength) side of the spectrum...like IR and visible light as opposed to harmful radiation such as UV and X-Rays on the higher energy side.

How To

How to determine X ray magnification factor?

Your magnification factor is SID divided by OID. [MF = SID/OID]

So for example:

If your SID was 40 and your SOD was 32

Your magnification factor = 40/32 = 1.25 -- This means the image will appear 25% larger than the actual object. (It's the size of 1 plus 25 percent more of the original.)

Example 2 if you're trying to figure out original object size:

Your object size equals your image size divided by the magnification factor (MF). [object size = image size/ MF]

If you have an object on an image that measure 70 inches when your SID was 100 and your OID was 65, how big was the original object?

MF=100/65= 1.54 (rounded)

Object size = 65/1.54 = 42.21

The object imaged was 42.21 inches before magnification.

Sunscreen is used to protect the skin from exposure to which type of solar radiation Visible X-rays Infrared Ultraviolet Microwaves?

Sunscreen is used to protect the skin from ultraviolet radiation emitted primarily by our sun. The ozone layer also protects us from ultraviolet rays, however the current problems with holes in the ozone layer makes wearing sunscreen almost essential if one is going to be outside for an extended period of time.

Why can't X-rays pass through lead?

X-rays can pass through lead. X-rays can pass through just about everything. Therapeutic level x-rays can pass through 10 feet of concrete and lead. However, in diagnostic x-ray only 1/4" of lead in the protective aprons is necessary to block most of the x-rays at that level of radiation.

X-rays actually can pass through lead.

But the amount of X-rays that is blocked is proportional to the density.

E.g. Water has density 1 and lead has density 11.36. Therefore water lets pass 11.36 times more X-rays than lead.

Which sorts of materials are transparent to x-rays?

X rays are are able to penetrate less dense materials easily, such as muscle and skin tissue in medical situations or plastics and wood in other applications.

As the material becomes more dense, the x rays penetrate less easily.

Materials such as steel or bone in a medical setting are more dense along with such materials as lead and tungsten in engineering situations.

What Does Radiolucent mean that it can not be seen on a x ray or an ct scan?

Radiolucent indicates a structure which lets relatively more x-rays through than the adjoining structures. The radiolucent structure is black on film, and the radio-opaque structure is white. Everything is relative. From radiolucent to radio-opaque, in a progressive order are air, fat, water (soft tissues), bone, metal.

What does an overexposed x-ray look like?

It depends on how overexposed it is. Overexposed means the image is too dark to be of acceptable diagnostic quality because some image details may be lost (burned out). Overexposed can mean it is a bit too dark, or it can mean the entire image is completely black.

Do X rays travel through space faster than radio waves?

No. The speed of all electromagnetic radiation in a vacuum is constant, that is, the speed of light.

Their frequency is much higher though, which makes them higher energy and more damaging to be exposed to. For example, if two guns were shot at a target, and both guns shot bullets at the same speed, but one gun shot 1 bullet per second (microwaves) and the other shot 5 bullets per second (x-rays). The bullets are traveling the same speed but the second gun would do more damage to the target in a much smaller span of time.

What is the difference between Soft X-ray Absorption Spectroscopy and Hard X-ray Absorption Spectroscopy?

The 'soft' and 'hard' refer to the energy of the x-rays used to perform the spectroscopy. Hard x-rays are higher energy x-rays than soft x-rays. Where to draw the line for when an x-ray stops being 'hard' and becomes 'soft' is rather arbitrary but most people would agree I think that x-rays of energy ~ 1500 eV and less are 'soft' x-rays and above ~ 2500 eV are 'hard' x-rays.

Can too much radiation from x-rays and ct-scan cause infertility in men?

Yes but the level of exposure that the average person would have to receive in order for that to occur is typically more than the typical diagnostic exposure time a patient would receive on a single visit. While CT's to give the most exposure at one time, unless it was a direct shot to the testes, one CT is unlikely (thought not impossible. There are rare exceptions to all cases with radiation) that it would happen. X-rays are far lower dosage and shielding of a patient's reproductive organs is typically done by technologists at all possible times.

Compare x-ray monogram to sonogram monogram?

it is a mammogram uses xrays and is cheaper and detects cysts etc
and their exact locations

sonography or breast ultrasounds can detect if the cyts is a solid or liquid
and can get right inside of the cyst found on the mammogram

both exams work well together making it helpful in the diagnosis

if your doctor has ordered either it is best to follow orders
