rad 103 properties of xrays

xrays travel in what kind of line

straight

what shape is an xray beam

cone

xrays lead to a what?

central ray

another name for xrays

photon

what is a photon

particle of energy. another name for xray.

heterogenous beam

all beams energies are a bit different

polyenergentic beam

multiple different energies

xrays are highly _____

penetrating

where do lower energy xrays go in relation to the body

get absorbed

where do higher energy xrays go in relation to the body

go through body

how do you see xrays

xrays are invisible

speed of xrays

speed of light

speed of light

3×10^8 m/s

what happens when xrays hit a body

ionization and scatter radiation

what happens to photons in the body

can be absorbed, pass through and hit IR, and hit something and scatter.

largest source of personnel exposure

scatter radiation

effects of scatter radiation

lowers and decreases contrast, increase patient dose, increase personnel dose

xrays affect _____ _____

photographic emulsions

areas with high radiation dose- high receptor exposure will appear

dark

areas with low radiation dose- low receptor exposure will appear

light

xrays cause some materials to ____?

fluoresce

what glows when hit by radiation

phosphurs

xrays do what to matter

ionize it

xrays cannot be ____ by a pens and cannot be ____ or ____

focused, reflected, retracted

xrays have no ____ and ____

mass, charge

how do xrays travel

isotropically

how are xrays made

heat filament, anode gets a positive charge and pulls/attracts negative electrons, electrons move to anode, xray is produced isotropically, wanted xrays come out of window
