Why is ultrasound less dangerous than x-rays?
Ultrasound is less dangerous than x-rays because it does not use ionizing radiation. X-rays have the potential to cause damage to cells and DNA due to their high energy level, which can increase the risk of cancer. In contrast, ultrasound uses sound waves to create images, which are considered safe and do not pose any known risks to human health.
How many non-zero angles are formed in a fan of 17 rays?
136 * * * * * Actually there are 17*16 = 272 angles. Assuming the rays do not meet at 180 degrees, each pair of rays forms two angles: one less than 180 deg and one greater.
How many non zero angles are formed in a fan of 30 rays with common angles?
Assuming none of the rays meet at 180 degrees, each pair of rays gives rise to two angles: one less than 180 deg and one greater. There can, therefore, be a maximum of 30*29 = 870 angles. (There are 435 unique pairs of rays: ab, ac, ad...bc, bd, be, etc.)
What is ultrasound?
Ultrasound is sound which has a frequency higher than that of audible sound.( like radar )ADDED: Not like radar. That uses radio waves, although sonar and radar principles are similar.
Is 8.7-0.26 greater or less than 8?
Less
Are X-rays less dangerous to health than ultraviolet radiation?
No, they are not. X-rays have a higher energy than UV radiation, and they have the potential to do more damage to tissue.

Are gamma rays more dangerous than x rays?
Yes, of course.
Why are ultrasound waves used for pre natal scanning rather than x rays?
Because of safety of the fetus, and x-rays really only give an idea of bone structure , whilst ultrasound gives us an indication of lung and heartdevelopment. :)
What is the standard size of a ultrasound room?
accepted is not less than 7 sqm.
Why are the sun's rays more dangerous on the moon than on earth?
Because the Moon has no atmosphere to filter out dangerous radiation.
Why ultrasound rather than x ray is used to scan expectant mother?
Two reasons. Firstly, Safety. Fetus have a higher rate of cellular division than the average human being. A damaged gene while still developing can cause birth defects. Secondly, X-rays really only give an idea of bone structure and generally aren't live. It X-rays don't give as clear an indication on lung and heart development.
Which is more dangerous uv or x-rays?
X-rays are more dangerous as they have a higher energy than UV radiation. The higher the energy, the more potential for DNA damage.
What are the advantages of using ultrasound instead of xray?
it does not damage tissues with ionizing radiation. Ultrasound is also generally far better than plain x rays at distinguishing the subtle variations of soft tissue structures, and can be used in any of several modes
How painful is a prostate ultrasound?
There is some discomfort, but less than most patients expect.
Are there any Ultrasound Technician Schools that can be completed in less than a year?
Yes, you can complete the ultrasound technician in less than one year. Many technical schools, Junior colleges and Universities offer ultrasound technician training classes for this fast track career that can land you a job in as little as one year.
Are alpha radiation dangerous?
Any electromagnetic radiation can be dangerous. Alpha waves are higher on the radiation scale than x-rays so yes, they are dangerous.
