Hello,

No, radioactivity is not included in the current JEE Main syllabus .
NTA has removed the full chapter from the Physics syllabus. This includes:

• Alpha, beta, gamma radiations

• Properties of these radiations

• Radioactive decay law

• Related formulas and concepts

So you do not need to study radioactivity for JEE Main.

Hope it helps !
