Some one said that during kurukshetra war pandavas used atomic bombs , which could destroy every thing as well as kauravas. And now archealogical survey discovered some radiation and till now there is no single grass in kurukshetra... is it true? Please give some detailed information!!

I don't know how anyone could give you more details on that war. It occurred possibly 6000bc. Yes, have read about the radiation but thought in a few circles that the lords of that time in battle were assisted by aliens. So go figure.
