nonradioactive
Emits no radiation
Nonradioactive describes substances that do not emit ionizing radiation.
The term appears in scientific and medical contexts to distinguish stable isotopes or materials from their radioactive counterparts: nonradioactive tracers, nonradioactive waste.
Something nonradioactive poses no radiation hazard.
