Ege \u00dcniversitesi N\u00fckleer Bilimler Enstit\u00fcs\u00fc M\u00fcd\u00fcr\u00fc Prof. Dr. Sabriye Yu\u015fan, g\u00fcnl\u00fck hayat\u0131n rutini i\u00e7inde kar\u015f\u0131la\u015f\u0131lan ve kimi zaman faydalar\u0131, kimi zaman zararlar\u0131 ile g\u00fcndeme gelen radyasyon ve radyasyonun insan sa\u011fl\u0131\u011f\u0131 \u00fczerindeki etkilerine y\u00f6nelik a\u00e7\u0131klamada bulundu. Prof. Dr. Yu\u015fan, \u201cRadyasyonun temel olarak, fizik, kimya, biyoloji, t\u0131p, eczac\u0131l\u0131k, tar\u0131m ve di\u011fer bilimsel alanlarda ara\u015ft\u0131rma yapmak i\u00e7in \u00f6nemli bir ara\u00e7lardan biridir ve gelecekte bu bilimsel alanlar\u0131n daha da geni\u015fleyece\u011fi ka\u00e7\u0131n\u0131lmazd\u0131r. Ancak unutulmamal\u0131d\u0131r ki radyasyonun kullan\u0131m\u0131yla ilgili g\u00fcvenlik ve \u00e7evresel endi\u015feler de g\u00f6z \u00f6n\u00fcnde bulundurulmal\u0131 ve uygun \u00f6nlemler \u00e7er\u00e7evesinde ve protokollere ba\u011fl\u0131 kal\u0131narak \u00e7al\u0131\u015fmalar s\u00fcrd\u00fcr\u00fclmelidir\u201d diye konu\u015ftu.<\/b><\/p>\n

Radyasyonun bir kaynaktan enerjinin elektromanyetik dalgalar veya par\u00e7ac\u0131klar \u015feklinde yay\u0131lmas\u0131 veya aktar\u0131lmas\u0131 oldu\u011funu s\u00f6yleyen Prof. Dr. Yu\u015fan, \u201cGenellikle elektromanyetik dalga ve par\u00e7ac\u0131k olmak \u00fczere iki ana tipe ayr\u0131l\u0131r. Elektromanyetik radyasyon, elektromanyetik alanlar arac\u0131l\u0131\u011f\u0131yla yay\u0131lan enerjinin bir formudur. G\u00fcne\u015ften gelen \u0131\u015f\u0131k, radyo ve televizyon sinyalleri, X \u0131\u015f\u0131nlar\u0131 ve cep telefonlar\u0131ndan yay\u0131lan sinyaller elektromanyetik radyasyona \u00f6rnektir. Par\u00e7ac\u0131k radyasyonu ise atomik ve n\u00fckleer olaylar sonucunda ortaya \u00e7\u0131kan y\u00fckl\u00fc par\u00e7ac\u0131klar\u0131n yay\u0131lmas\u0131d\u0131r. Bu t\u00fcr radyasyon, genellikle n\u00fckleer reakt\u00f6rler, radyoaktif maddeler ve kozmik \u0131\u015f\u0131nlardan kaynaklanmaktad\u0131r. Ayr\u0131ca, par\u00e7ac\u0131k radyasyona alfa ve beta \u0131\u015f\u0131nlar\u0131 ile n\u00f6tronlar \u00f6rnek verilebilir\u201d dedi.<\/p>\n

\u0130nsan\u0131n g\u00fcnl\u00fck hayat\u0131nda radyasyonun \u00f6nemli bir yer kaplad\u0131\u011f\u0131n\u0131 vurgulayan Prof. Dr. Yu\u015fan, \u201cT\u0131pta hastal\u0131klar\u0131n te\u015fhis ve tedavi edilmesi i\u00e7in X \u0131\u015f\u0131nlar\u0131 ve radyoterapi gibi teknikler, g\u0131dalar\u0131n i\u015flenmesi, korunmas\u0131, raf \u00f6mr\u00fcn\u00fcn uzat\u0131lmas\u0131, tohum-bitki \u0131slah\u0131, tar\u0131m verimlili\u011finin art\u0131r\u0131lmas\u0131, yeralt\u0131 suyunun ak\u0131\u015f\u0131n\u0131n izlenmesi, yeralt\u0131 kaynaklar\u0131n\u0131n haritalanmas\u0131 ve malzeme dayan\u0131kl\u0131l\u0131\u011f\u0131n\u0131n artt\u0131r\u0131lmas\u0131 gibi alanlarda kullan\u0131lmaktad\u0131r\u201d dedi.<\/p>\n

\u201cYasal d\u00fczenlemelere uyulmal\u0131\u201d<\/b><\/p>\n

Radyasyon kullan\u0131m\u0131n\u0131n, belirli g\u00fcvenlik protokolleri ve lisanslama s\u00fcre\u00e7leriyle d\u00fczenlendi\u011fine dikkat \u00e7eken Prof. Dr. Yu\u015fan, \u201cRadyasyon kullan\u0131m\u0131yla ilgili yasal d\u00fczenlemelere uyulmal\u0131 ve yetkilendirilmi\u015f kurulu\u015flar taraf\u0131ndan verilen lisanslar al\u0131nmal\u0131d\u0131r. Uyulmas\u0131 gereken temel prensiplerden biri de Radyasyon Dozunun Kontrol\u00fc olup; radyasyona maruz kalma d\u00fczeyi, m\u00fcmk\u00fcn olan en d\u00fc\u015f\u00fck seviyede tutulmal\u0131 ve radyasyon dozunu kontrol etmek i\u00e7in dozimetri cihazlar\u0131 kullan\u0131lmal\u0131, maruz kalma seviyeleri izlenmelidir. Personel, radyasyonun potansiyel riskleri konusunda bilgi sahibi olmal\u0131 ve g\u00fcvenli \u00e7al\u0131\u015fma prosed\u00fcrlerini mutlaka uygulamal\u0131d\u0131r. Radyasyon yayan cihazlarla \u00e7al\u0131\u015fan ki\u015filer Radyasyondan Korunma Sorumlusu belgesi mutlaka almal\u0131d\u0131r. Ayr\u0131ca, gereksiz radyasyon uygulamalar\u0131ndan ka\u00e7\u0131n\u0131lmal\u0131 ve yaln\u0131zca gerekli durumlarda kullan\u0131lmal\u0131d\u0131r. Radyasyon kullan\u0131m\u0131nda, \u00e7evresel ve toplumsal etkilerin dikkate al\u0131nmas\u0131 ve bu s\u00fcre\u00e7te \u00f6zellikle radyasyon kaynaklar\u0131n\u0131n depolanmas\u0131, ta\u015f\u0131nmas\u0131 ve imhas\u0131 gibi prosesler \u00e7evresel etkileri en aza indirmek i\u00e7in uygun prosed\u00fcrler \u00e7er\u00e7evesinde y\u00f6netilmelidir. Bu nedenle, radyasyonun kullan\u0131m\u0131yla ilgili herhangi bir faaliyet, titizlikle planlanmal\u0131, uygulanmal\u0131 ve izlenmelidir \u201d diye konu\u015ftu.<\/p>\n

\u201c\u00c7evresel endi\u015feler g\u00f6z \u00f6n\u00fcnde bulundurulmal\u0131\u201d<\/b><\/p>\n

Nisan 1986\u2019da ger\u00e7ekle\u015fen; insan, hayvan ve bitki d\u00fcnyas\u0131n\u0131 derinden etkileyen \u00c7ernobil N\u00fckleer Kazas\u0131nda radyasyon nedeniyle pek \u00e7ok genetik de\u011fi\u015fim meydana geldi\u011fini ifade eden Prof. Dr. Yu\u015fan, \u201cRadyasyon genetik dizilimi DNA hasar\u0131, kromozom k\u0131r\u0131lmas\u0131 ve gen ekspresyonu de\u011fi\u015fmesi \u015feklinde etkilemektir. DNA hasar\u0131, genetik materyalin bozulmas\u0131na ve h\u00fccrelerin normal i\u015flevlerini yerine getirememesine yol a\u00e7abilir. Bu hasar, h\u00fccre b\u00f6l\u00fcnmesi s\u0131ras\u0131nda kal\u0131c\u0131 mutasyonlara ve genetik de\u011fi\u015fikliklere yol a\u00e7abilir. Y\u00fcksek d\u00fczeyde radyasyon maruziyeti, kromozomlarda k\u0131r\u0131lmalar ve anormalliklere neden olmaktad\u0131r. Bu, h\u00fccre b\u00f6l\u00fcnmesi s\u0131ras\u0131nda yanl\u0131\u015f kromozom da\u011f\u0131l\u0131m\u0131na ve genetik materyalin de\u011fi\u015fmesine yol a\u00e7maktad\u0131r. Son olarak da Gen Ekspresyonunu de\u011fi\u015ftirebilmekte ve bu s\u00fcre\u00e7te h\u00fccrelerin normal fonksiyonlar\u0131n\u0131 etkilenip, genetik materyaldeki de\u011fi\u015fiklikler ortaya \u00e7\u0131kabilir\u201d dedi.<\/p>\n
