- Gold-201 is a beta/gamma emitter with a 26 minute halflife.
- Mercury-201 is stable and makes up 13.22% of natural Mercury.
- Thallium-201 is a gamma emitter decaying by K capture with a 72 hour halflife.
- Lead-201 is a gamma emitter decaying by K capture with a 8.4 hour halflife (or less depending on isomer).
Other elements can be produced with an AMU number of 201, but there halflives are really too short to be of practical interest.
