The Application ofNuclear Technology inAgriculture and Food


2/30

INTRODUCTION

• Generally, it is believed that nuclearenergy is used for destructive purposesonly.

• But, in fact, it has more positive uses thanits negative uses.

• Basically atom is the source of nuclearenergy. This energy is released by splitting

of a nuclei into two

DI"AD$ANTAGE OF FOODIRRADIATION

• 5t can only be used on a verylimited range of foods. %fresh milk,margarine, star fruit'

• 5t is still a relatively e*pansivetechnology. %high cleanup costs'

• 1itamin $ levels can be reduced by

647 after irradiation and vitamin" by 4)37.

• 5t is ine8ectively against viruses.

*2 Fertilisers• Fertilisers are e*pensive and if not properly

used can damage the environment.

•

5t is important that as much of the fertiliseras possible ;nds its way into plants and thata minimum is lost to the environment.

• $*posing plants to radiation is sometimes calledradiation breeding.

• 5t was discovered in the 3>6s when ?ewisStadler %9niversity @issouri' used *)rays onmai!e and barley.

• @utation breeding is commonly used to producetraits in crops such as larger seeds, new colors orsweeter fruits that either cannot be found innature or have been lost during evolution.

/2 IN"ECT" CONTROL•"rop losses caused by insects mayamount to more than 37 of the totalharvest worldwide

•Some insects have become resistant tothe chemicals used, and some

insecticides leave poisonous residues onthe crops. Ane solution has been the useof sterile insects.

The "terile InsectTechni@ue ="IT'

• 5t involves rearing large numbers of maleinsects with gamma radiation before hatching,to sterilise them.

• The sterile males are then released in largenumbers in the infested areas to compete withwild fertile males for mature female insects.

• hen they mate with females, no o8spring are

produced. ith repeated releases of sterilisedmales, the population of the insect pest in theproCect area is drastically reduced

• These pests included the @editerranean fruit &y

and the screwworm &y.
