As a subject matter expert in the field of biology and popular culture, I can provide you with a detailed explanation of what a "radioactive spider" typically refers to in both scientific and fictional contexts.

In a scientific context, a radioactive spider would be a spider that has been exposed to ionizing radiation. This exposure could potentially lead to genetic mutations or other biological changes, although the actual effects would depend on the type and level of radiation, as well as the duration of exposure. It's important to note that the concept of a radioactive spider causing superhuman abilities, as seen in comic books, is purely fictional and not grounded in scientific reality.

In popular culture, particularly in the Marvel Comics universe, a radioactive spider is a fictional element that plays a crucial role in the origin story of Spider-Man. In this narrative, a young Peter Parker is bitten by a spider that has been accidentally exposed to radioactive material. This bite grants him spider-like abilities, such as climbing walls, enhanced strength, and a "spider-sense" that alerts him to danger.

To summarize, a radioactive spider in a real-world scientific context is a creature that has been exposed to radiation and could potentially experience biological changes as a result. In fiction, especially within the Spider-Man storyline, it is a plot device that leads to the creation of a superhero with extraordinary powers.
