With a geiger counter. It can detect radioactive particles. That is the most common, modern way. In Ernest Rutherford's 'Gold Foil' Experiment, he visible saw radioactive particles by using a sheet of Zinc Sulfide that lit up when it was hit by an alpha particle (form of radiation).

∙ 13y agoIt means that the atoms inside the substance are not stable; the nuclei in these atoms can decay. This changes one type of atom into another and releases radiation (the exact type of radiation depends on the substance). Types of radiation are gamma rays, electrons/positrons or helium nuclei.
