Among the man-made sources of ionising radiation medical X-ray units contribute the highest radiation dose to the public12. In Kerala too the fact remains the same where 150 X-ray examinations are conducted per 1,000 people every year and more than 3.6 million people per year undergo X-ray investigations3. The X-ray doses received were in the range of 0.5 mSv to 30 mSv with a very large standard deviation. Patient doses in respect of a wide variety of X-ray investigations are actually measured and presented.
