Rad Tech Scientific Notation, is the subject today where we cover the physics essentials of Scientific Notation if you are beginning out as a Radiographer or Technologist and want to be clear on the conversion of clinical systems.

For more details on x-ray and CT physics please see our website https://howradiologyworks.com

This is effective stuff, pun planned. As we are dealing with powers of 10 today.

Here at how radiology works our company believe clinical notation is really valuable.

You don’t want to invest your whole life writing nos behind numbers or zeros in front of numbers so clinical notation conserves us a ton of time and helps be extremely clear about how we can reveal numbers specifically helpful for really big numbers or really little numbers for radiologic technologists or radiographers a lot of the time you’re going to be handling systems that are kilovolts or milliamps and you wish to know exactly what those mean.

Here is the table for Scientific Notation that we will go through in this video.
Prefix Symbol Factor Power
———————————
giga G 1000000000 10 ^ 9
mega M 1000000 10 ^ 6
kilo k 1000 10 ^ 3
hecto h 100 10 ^ 2
deca da 10 10 ^ 1
( none) (none) 1 10 ^ 0
deci d 0.1 10 − 1
centi c 0.0110 − 2
milli m 0.00110 − 3
micro μ 0.000 00110 − 6
nano n 0.000000 00110 − 9

What does the kilo indicate in respect to the units that we’re talking about so at a high level we’re simply talking about powers of 10 so 10 to the n and for 10 to the n we’re talking about for circumstances if you simply have 10 to the 1, anything raised to the 1 is that exact same number right so that’s simply 10.

Examples:
Convert 3eV to keV?
We require to multiple by 10 ^ -3 considering that keV is 10 ^ 3 larger system so the answer is 0. 003 keV, which reveals just how much lower energy blue light has than the x-ray energies in the diagnostic spectrum which are 10-140 keV for example.

Transform 140 kV to V as we are more used to the unit of volts for example as an automobile battery is typically 12 V?
We need to increase by 10 ^ 3 considering that kV is 10 ^ 3 bigger system than V. This is the very same as adding 3 additional nos, so we get 140 kV = 140,000 V.

Please attempt some examples by yourself as you study your ARRT product.
