Title
The Absorption Coefficient for γ - ray and the Thermal Expansion coefficient of Ni - Activated Sintered W - Powder Compacts
김영환Young Hwan Kim, 서룡호Yong Ho Suh, 문인형In Hyung Moon
Abstract
The absorption coefficient for γ-ray as well as thermal expansion coefficient was determined in the Ni-activated sintered W-powder compact, in order to examine whether the low-temperature sintered W-product can be substituted for the normal sintered W-product in radiation shield and high temperature application. The measured half value layer of the activatedly sintered W-specimen was thicker than that of the normal sintered pure W-specimen by 10-14%. However, the measured thermal expansion coefficient of the former was comparable to that of the latter in the range of temperature investigated in the present work.
