A lightbulb in your house does not emit harmful radiation. It typically emits visible light and a minimal amount of heat. However, it is important to note that all objects with a temperature above absolute zero (-273.15°C or -459.67°F) emit a form of electromagnetic radiation known as thermal radiation. This radiation, in the case of a lightbulb, is generally in the form of infrared light (which is not harmful in small amounts). Nonetheless, the amount of radiation emitted by a typical lightbulb is considered safe for everyday use.
