BACKGROUND

Gamma radiation has been widely used inindustrial processes, especially in foodprocessin! Gamma radiation can induce certainalterations that can modify both the chemicalcomposition and the nutritional "alue of foods!

#ood irradiation is a technoloy for controllin

spoilae and eliminatin food$borne pathoensthat may be present in food!

Radiation is the only treatment that can be

applied to foods throuh any type of pac%ainmaterials includin paper, plastic, wood and

(o identify essential mineral elements ofcucumber (Cucumis sativus).

(o obser"e the eect of amma radiation on

trace element of cucumber (Cucumis sativus) by (andem Accelerator!

(o re"eal the nutritional composition of

cucumber (Cucumis sativus) by neutronacti"ation analysis!

(o obser"e the eect of amma radiation onminerals content of cucumber (Cucumissativus) by neutron acti"ation analysis!

Tandem Accelerator

(andem accelerator is a type of accelerator toaccelerate ions by applyin an electrostatic-eld with a feature of supplyin hih "oltae

in the middle of acceleratin tube! )t canaccelerate ions in two steps. -rst,acceleratin neati"e ions and second,further acceleratin positi"e ions aftertransformin neati"e ions into positi"e inthe hih$"oltae terminal!

,ses + Method of Tandem Accelerator

(he tandem accelerator is used for theelemental composition analysis of solids!

(he tandem accelerator also ser"es as the ion$in/ector for the synchrotron accelerator, so thataccelerated protons are sent to the synchrotronaccelerator!

0articles in the synchrotron accelerator tra"elaround the trac% 1 million times maintainin a

-2ed orbit by manetic intensity enerated by

Neutron Acti"ation Analysis

Netron Acti-ation Anal#sis 5NAA" is a 6antitati-e and

6alitati-e method of hi*h efficienc# for the (recise

determination of a nm!er of main/com(onents and trace

elements in different t#(es of sam(les&

Neutron Acti"ation Analysis 3NAA4 is used tomeasure trace$ and ultra trace$elementconcentrations of impurities in semiconductorsand other hih$purity materials!

)ood Radiation

#ood irradiation is a process in which appro"ed foodsare e2posed to radiant enery, includin amma rays,electron beams, and 2$rays to ma%e them free frommicrobes 5 thus e2tend their self life!

(he 6dose6 for food irradiation is the amount ofradiation absorbed by the food and it is not the same asthe le"el of enery transmitted from the radiationsources! (he dose is controlled by the intensity ofradiation and the lenth of time the food is e2posed!

Radiation has been identi-ed as a solution thatenhances food safety throuh the reduction of potentialpathoens and has been recommended as part of acomprehensi"e proram to enhance food safety !

Cobalt$78 is the most commonl used radionuclide for

S,MMARY AN$ CONCL,SION

Cucumbers are a nutritious fruits that can help weihtloss, reduce ris% of chronic disease and help body form

healthy /oints! A sinle medium cucumber contains morethan @ m of "itamin C! hich is important for buildinconnecti"e tissue and -htin o2idation!

)n this study it is obser"ed that the essential mineralcontent of Cucumis Sativus 3Cucumber4 is sensiti"e toirradiation doses! (here are "arious eect are obser"ed onthe essential mineral contents of Cucumis Sativus

3Cucumber4by dierent types of radiation doses!
