This paper shows how plasmas are produced due to ion irradiation and discusses relaxation of these plasmas through simulation studies. The effect of these plasmas on the track structures is also discussed. In some theoretical studies, these plasmas were predicted and this effect was shown more than 35 years ago. However, no simulation studies report this effect before our studies. It is found that these plasmas play a role of bringing high local doses near the track of an incident ion. Such high local doses are expected to contribute significantly to the production of clustered DNA damage.
