e·mis·sion

(ē-mish'ŭn),
A discharge; usually referring to a discharge of the male internal genital organs into the internal urethra; the contents of the organs, including sperm cells, prostatic fluid, and seminal vesicle fluid, mix in the internal urethra with mucus from the bulbourethral glands to form semen.

2. an involuntary discharge of semen.

nocturnal emission  reflex emission of semen during sleep.
positron emission  a form of radioactive decay in which a positron (β+) and neutrino are ejected from the nucleus as a proton is transformed into a neutron. Collision of the positron with an electron causes annihilation of both particles and conversion of their masses into energy in the form of two 0.511 MeV gamma rays.

emission

Etymology: L, emittere, to send out
a discharge or release of something, as a fluid from the body, electronic signals from a radio transmitter, or an alpha or beta particle from an atomic nucleus during radioactive decay.
