【Awards and Commendations】Masafumi OZEKI(M2), Department of Nuclear Engineering and Management won Annual award at 17th PASJ2020.

On September 4th, 2020, Masafumi OZEKI(M2), Department of Nuclear Engineering and Management won Annual award at 17th PASJ2020.  Awards aimed at encouraging students and young researchers in the early stages of research activities and research life.


Title:
Study of Ra-225 / Ac-225 production using an electron linac

Summary:
The radiopharmaceutical 225Ac-PSMA-617 is a treatment for prostate cancer using Ac-225, and is expected as a new treatment method.
In order to promote clinical research in Japan, I conducted a basic study of the Ac-225 manufacturing method using electronic linac.
When a Ra-226 target is irradiated with γ-rays, Ra-225 is produced by the 226Ra(γ,n)225Ra reaction.
Ac-225 can be obtained by natural decay from Ra-225. This time, the yield of Ac-225 and the heat of the Ra-226 target during irradiation were calculated.


Thanks to the great support of around me, I received an honorable award.
In the future, I will proceed with the Ac-225 producing experiment at ELPH.
