You are Radiologist by profession married since six months and unable to impregnate your wife. There are two possible reasons for not conceiving 1 Excessive smoking 2 Frequent exposure to radiation at your work place You need to use marker to estimate the amount of radiation exposure that you are subjected to every day.
