We have used polycarbonate track-recording films to confirm the rare decay mode of /sup 226/Ra by /sup 14/C emission and to set stringent upper limits on /sup 14/C-emission rates of /sup 221/Fr, /sup 221/Ra, and /sup 225/Ac. The /sup 14/C-emission rate exhibits a pronounced odd-even effect. For Ra isotopes the hindrance factor for odd-even parents relative to even-even parents is at least 10 times higher for /sup 14/C emission than for ..cap alpha.. emission.
