229 를선택적으로발생시키기위해서는초음파입사각의변경이가능해야한다. 이를위해서그림 4.1.7과같은가변각웨지 2개를설계, 제작하였다. 초음파의왜곡이발생할수있는접합계면을없애기위해서특수가공으로제작되었으며, 재질은 Plexiglass로써종파속도 2720 m/s 이다. 그림 쐐기도면 ( 라 ) 초음파탐촉자 (Probe) 초음파탐촉자는그림 과같은 Panametrics INC. ACCUSACN-S, 사각형탐촉자 0.5, 1.0, 2.25, 3.5 MHz 를사용하 였다

363 Version: 1.0 Entered-date: 12 Jan 1997 Description: rt starts any program on realtime priority, like nice does with lower priority. Lets you choose scheduler class (SCHED_RR vs SCHED_FIFO policy) and priority. Keywords: linux, real time, scheduler Author: Boris Tobotras Maintained-by: Boris Tobotras Primary-site: sunsite.unc.edu /pub/linux/system/admin 10 kb rt-1.0.tar.gz Alternate-site: ftp.macsimum.ru /pub/linux/local 10 kb rt-1.0.tar.gz Platform: Linux and later Copying-policy: GPL End

467 더이상의감소가나타지않은것으로보인다. 연신율의결과에서 PA-1이 200 kgy의선량에서다른시편에서보다연신율의감소정도가적게나타나며 HDPE와유사한특성을지녀우수한내방사선특성을나타낸것으로볼수있다. 방사선조사에따른배합 PE의접촉각변화를그림 6.3.7에나타내었다. 일반적으로방사선조사에따른 ester 결합을포함하는고분자는방사선에의해라디칼을형성하고, β-scission에의해 -OH기를더많이갖는 ester 를형성하여, 소수성이급격히감소하게되지만, 조사량이더증가하여 phthalate의형성도많아지게되면소수성이다시증가하게된다 [6.39]. 그러나 ester 결합을갖고있지않는경우의고분자는방사선조사선량이증가할수록공기중의산소와반응하여알콕시라디칼 (RO ) 을형성하고, 이렇게형성된라디칼들이주쇄를공격하여주쇄에카르보닐기 (-C=O) 이나하이드록시기 (-C-OH) 를형성하게되어고분자표면의소수성을감소시키게된다. 또한조사량이더증가하면알콕시라디칼의농도가증가하게되고, 표면의산화에그치지않고고분자주쇄를절단 (scission) 하거나, 고분자간의가교를유도하기도한다 [6.40]. 첨가제의종류에따른배합 PE 의방사선조사에대한접촉각변화는초기방사선미조사경우에높은접촉각을보였으나조사선량의증가에따라접촉각이감소하는경향을나타내고있다
