”X光” 問題!

1. 1次照咁多 ,會有乜後果?
I presume you have been taken conventional chest X-ray radiography. A chest X-ray would deliver an effective dose of about 0.06 mSv (mSv is a unit for radiation dose). You have taken 6 chest X-rays, the total dose you received is 6 x 0.06 mSv = 0.36 mSv

The level of dose is low as compared with the normal background radiation of about 2.5 mSv with which an average would receive in a year. Hence, the dose received by you in the 6 chest X-rays is only 14% of the natural background.

It is for sure that for radiation dose below 100 mSv, no adverse health effect would occur. You don't have to worry about such dose from the radiological chest examination.

In fact, if you undergo a CT X-ray examination (電腦掃瞄), the dose is even higher. A typical CT examination of the chest will deliver an effective dose of about 7 mSv. Even in the so-called "low dose" CT chest X-ray examination, a dose of about 3 mSv will be received by the patient.

The second question is NOT a physics question. You may wish to post it in the "medical section".
