Brief Answer: Do not worry Detailed Answer: Hi, Thanks for writing in to us. I have read through your query in detail. Your question is very important I hope to provide you with an acceptable answer as a Radiologist. Radiation exposure is measured in milli Sieverts mSv . The dose of 2 mSv is a very small dose and equal to the amount of radiation exposure that is absorbed by a person working as an inflight air crew member who travels in aeroplane each day for a year (annual dose). Having said that you should not be worried from the radiation causing any serious harm to you. I must say the machine is really good if it is a 160 slice CT with dose limitation capabilities. Hope your query is answered. Do write back in case of doubts. Regards. Dr.Vivek
