Room Temperature Annealing Process of Recoil Fragments in Neutron Irradiated Ammonium Chromate

상온에서 (NH$_4$)$_2$CrO$_4$를 원자로에 조사하고, 조사된 후 상온에서 보관된 시간과 $^{51}$ Cr의 잔류값을 반응속도론적으로 연구하였다. 또한 원자로 조사시간 변화에 따르는 $^{51}$ Cr의 잔류값을 반응속도론적으로 고찰하였으며 일차반응으로 표시 될 수 있었다.

The retention of $^{51}$ Cr was studied as chromate after dissolution of irradiated ammonium chromate with reactor exposure time and various storage time at room temperature. The annealing process of ammonium chromate depending on various storage time at room temperature follows first-order kinetics from zero time value to the pseudo-equilibrium value. The retention is increased with reactor irradiation time, also following first-order kinetics.
