today we had our health screening at the company.
But I had a pass on the X-ray as I had one just about 3 months ago.
健康診断
けんこうしんだん
kenkou shindan
physical examination
X線
エックスせん
ekkusu sen
X-ray
レントゲン
roentgen

健康診断 is a very common word in Japan. Vocabulary acquired at work when our officemates take a leave to have their check-ups.
I cant be really sure but I thinkX線 is more widely used than レントゲン because it had an entry on wikipedia. レントゲン on the other hand returned image results in the first results page displayed (google).
