The nuclear reaction you're describing is the beta decay of Carbon-14. Here's the complete reaction:

¹⁴₆C → ¹⁴₇N + ⁰₋₁e + νₑ

Here's what's happening:

* ¹⁴₆C: Carbon-14, the parent nucleus, is unstable.

* ¹⁴₇N: Nitrogen-14, the daughter nucleus, is stable.

* ⁰₋₁e: This represents a beta particle, which is an electron emitted from the nucleus.

* νₑ: This is an electron antineutrino, a subatomic particle also emitted during the decay.

Therefore, the type of radiation emitted in this nuclear reaction is beta radiation (β⁻).
