Question 12

Radium-223 (Ra-223\text{Ra-223}Ra-223) is a clinically approved radiopharmaceutical used in targeted cancer therapy to treat bone metastases. During its primary decay, a Radium-223 nucleus (88223Ra^{223}_{88}\text{Ra}88223​Ra) transforms into a Radon-219 nucleus (86219Rn^{219}_{86}\text{Rn}86219​Rn).

Which type of ionising radiation is emitted during this decay step?

A

alpha

B

beta-minus

C

beta-plus

D

gamma
