ASSIGNMENT

 1.) Gamma rays

o Medical application: are used in medicine to kill and treat certain types of cancers and

tumors. Gamma rays passing troug tissue of te !ody produce ioni"ation in tissue.

Gamma rays can arm te cells in our !ody. Te rays can also detect !rain and

cardio#ascular a!normalities.

o Industrial application : Gamma rays can be used to examine metallic castins

or !elds in oil pipelines "or !ea# points. $%e rays pass t%rou% t%e metal and

dar#en a p%otorap%ic &lm at places opposite t%e !ea# points. In industry,

amma rays are used "or detectin internal de"ects in metal castins and in

!elded structures. Gamma rays are used to #ill pesticides and bus in "ood.Gamma rays are also used in nuclear reactors and atomic bombs.

'.( )*rays

o +edical use: )*rays in medical imain suc% as )*ray radiorap%y, computed

tomorap%y C$(,mammorap%y, aniorap%y and -uoroscopy. )*ray

imain creates pictures o" t%e inside o" your body. $%e imaes s%o! t%e

parts o" your body in dierent s%ades o" blac# and !%ite. $%is is because

dierent tissues absorb dierent amounts o" radiation.

o Industrial use: )*rays are used in industry to inspect products made by

/arious #inds o" materials. )*ray mac%ines are used in airports to c%ec#

luae etc.

0.( 1ltra/iolet rays

o +edical application: 1ltra/iolet !a/es are eecti/e in #illin bacteria and

/iruses. Hospitals use ermicidal lamps t%at produce t%ese !a/es to sterili2e

e3uipment, !ater and air in operatin rooms. It is also used to treat acne and

psoriasis.

o Industrial application: $%e 4ood and 5ru industry uses ermicidal lamps to

disin"ect /arious types o" products and t%eir containers. $%e main use o" 

ultra/iolet is in t%e manu"acturin interated circuits.

6.( In"rared rays

o +edical application: 5octors use in"rared lamps to treat s#in diseases and

relie/e t%e pain o" sore muscles. In t%ese treatments, t%e in"rared rays pass

t%rou% t%e patient7s s#in and produce %eat and it includes +icro!a/e Heat

 $%erapy a type o" medical treatment in !%ic% body tissue is exposed to

sli%tly %i%er temperatures to damae and #ill cancer cells or to ma#e

cancer cells more sensiti/e to t%e eects o" radiation and certain anti*cancerdrus.

o Industrial application: In"rared is used extensi/ely in specially*desined o/ens

"or dryin painted and enameled sur"aces, leat%er, metals, papers and

textiles.

8.( +icro!a/es

o +edical application: It is use in +icro!a/e ablation t%at pro/ides desiccation

o" tissue !it%out t%e excessi/e c%arrin and ner/e damae associated !it%

94 ablation. arious applications include treatment o" lare tumours or

remo/al o" un!anted tissue masses, "or example li/er tumours, lun tumours

and prostate ablation. +icro!a/es can also be used to coaulate bleedin in

%i%ly /ascular orans suc% as t%e li/er and spleen.

o Industrial application: +icro!a/es can decrease air pollutants, disin"ect

%ospital !aste, impro/e dry cleanin sol/ents, and clean up contaminated

soil.

;.( 9adio!a/es

o +edical application: 9adio !a/es are used to transmit t%e pattern o" a

%eartbeat t%rou% a monitor at a patient7s %ome to a nearby %ospital. $%ey

are also used to radio t%e condition o" a patient "rom an ambulance to a

%ospital. 9adio !a/es are used in medicine !%en paramedics are dispatc%ed

to t%e scene !%ere t%ey are needed. 4urt%ermore,Heat enerated by radio

!a/es erases most pre*cancerous cells associated !it% c%ronic acid re-ux,

pro/idin an alternati/e to surery or t%e current !ait*and*see approac%. It is

also use in ablation tec%noloy !or#s !%ic% %as t%e same principle as

"ree2in !arts o s#in, but uses %i% "re3uency radio !a/es s%ot t%rou% a

cat%eter to taret abnormal cells in t%e esop%aus.

o Industrial application: 9adios are also used in industry, mainly in t%e

transportation business. 9adio !a/es can also be used to pro/ide

communication on construction sites.

o +edical application: "or /isual in"ormation about a patient: color, structure,

mirror: "or op%t%almoscope, otoscope. Endoscope: Cystoscope "or bladder ,

Proctoscope "or rectum, =ronc%oscope "or air passaes to luns, Cold*li%t

endoscope: /ery little I9 radiation to minimi2e %eatin eect>

transillumination> t%erapeutic uses

o Industrial use: Lasers are used "or cuttin and !eldin procedures * mostly

!%ere small parts are in/ol/ed. Laser beams !eld !ires onto microcircuits

and repair damaed !ires inside lass tubes. =y alinin %ea/y mac%inery

e3uipment, a laser inter"erometer can control t%e operations o" mac%inery.

Lasers are able to cut teet% in sa!s. Lasers are also used to create per"ect

ri%t anles in place o" t%e traditional c%al#*line or $*s3uare.
