Remote-controlled System for a Large Scale Production of Short-lived Radioactive Substances with Cyclotron

—Development and Radioisotope Productions—

Abstract

A system was developed for producing short-lived radioactive substances (¹¹CO, ¹¹CO₂, ¹³NN, ¹³NH₃, ¹⁸F^-, ⁶²Zn²⁺, ¹²³I^-, etc.) on a scale enough for clinical use, which could also be used for analyzing them rapidly and for investigating their production methods, with less received dose by workers.
The system enabled us to produce remotely several tens mCi of short-lived radioactive substances readily usable for clinical diagnosis, continuously for radioactive gases, ¹¹CO, ¹¹CO₂ and ¹³NN, or repeatedly at short intervals for radioactive aqueous solutions of ¹³NH₃, ¹⁸F^-, etc. Employing this system, the average received dose per month was reduced considerably.
