hello everybody my name is Zohir Chowdhury, and today we'll talk about ionizing and non-ionizing
radiation radiation so that term radiation refers to energy traveling through space and
two types of radiation ionizing and non-ionizing ionizing radiation has enough energy to remove
tightly bound electrons from atoms thus creating miles its property are used to generate electric
power to heal cancer cells in many manufacturing processes some examples are alpha radiation beta
radiation and gamma radiation as well as x-rays the alpha radiation releases alpha particles and
the beta radiation releases partum made up of beta particles not analyzing radiation on the
other hand has just enough energy to move atoms in a molecules around or cause them to vibrate
but does not have enough energy to remove the electrons so for the ionizing case you're actually
has enough energy to remove direct transfers of non ionizing it doesn't have enough energy
to remove the electron example wise extremely low frequency radiation in power lines is an example
a.m. or FM radio station VHF TV radio waves also examples as well as microwave radiation inside the
microwave infrared radiation and the visible light and ultraviolet all are examples of non
ionizing radiation in this chart we can see the various ionizing and non-ionizing radiation in
the electromagnetic spectrum this is known as the electromagnetic spectrum and it shows the
frequency of the various radiation and wavelength of this radiation and they're categorized based on
frequency and wavelength so on the right side in here where we have high frequency and very
small wavelengths we can see ionizing radiation in here and we can see x-rays and gamma rays on
this end of the spectrum and why they are there ionizing as we mentioned earlier they can create
ions they can bring bonds as a result cause DNA damage and lead to cancer mutation and birth
defects on the left side of this electromagnetic spectrum right here if we draw a line in here this
is where we are dividing that ionizing from the non ionizing on the left side of the spectrum
we have the non ionizing radiation and we can look at them in three different parts known as
a radiation that are optically nature non amazing radiation there are thermal in nature and known
as ionizing radiation there are non thermal or produces low induced currents so the one that
are on this side they are known as that e.l.f or extremely low frequency radiation and this
is what we see in power line and static fields so very small frequency and very large wavelength on
the center in here we can see radiation there are thermal in nature that releases heat and examples
are radio frequency in the am/fm radio antenna as well as TV waves the TV signal travels to
air and also the signal in mobile phones and mic and microwaves they're all example of non
ionizing radiation that produces thermal Heat and right here in between to us the right side
of this spectrum very close to the non ionizing radiation we're into the diamond simulation we
have the infrared radiation or IR and these are the optical kind they produce electronic
excitation and releases light as a result so examples are infrared light heat lamps as well
as visible light the light that helps us to see from the Sun and ultraviolet as a light as well
and ultraviolet is right at the cusp between ionizing and non-ionizing radiation so some of
the ultraviolet rays does produce a little bit of the of ionizing radiation especially that UVC
kind located right in here okay again this is the same electromagnetic spectrum and it just shows
wavelength in here and some of the more popular item or things you may be familiar with and the
diameter of each of these places or the length of each of these things a corresponds to the
wavelength that you're seeing in here to give you an idea how those wavelengths are so for example
radio waves in here are each wave er is at the size of like a building microwave on the other
hand is much smaller and then as we go to gamma rays they are the size of atomic nuclei okay so
let's do some quick concept check alpha beta gamma radiation are examples of which type of radiation
ionizing radiation a very good which of the following is an example of non
ionizing radiation there are all examples of non ionizing radiation D thank you
