BTSC X-Ray Technician — 15 Important MCQs with Answers
Ye 15 sawal pichle standard exam sets aur radiation physics ke sabse high-frequency concept par aadharit hain. Pehle khud solve karein:
Explanation: Tungsten high heat withstand kar sakta hai kyunki 99% energy heat me convert hoti hai aur sirf 1% hi X-ray banti hai.
Explanation: 180 cm (6 feet) par cardiac magnification kam se kam hota hai jisse heart ka true size accurately dikhta hai.
Explanation: mAs X-ray photons ki total quantity tay karta hai, jo sidhe image blackening (density) ko control karta hai.
Explanation: kVp badhane se photons ki energy aur penetration power badhti hai jisse beam hard banti hai aur contrast ghat ta hai.
Explanation: Ye radiation protection ka basic guideline hai jisme Time, Distance aur Shielding se dose minimum rakhi jaati hai.
Explanation: CaSO4:Dy crystals radiation absorb karte hain aur heat karne par proportional light emit karte hain.
Explanation: Anode target material dwara beam absorb hone ki wajah se cathode side intensity lagbhag 20-30% zyada hoti hai.
Explanation: Diagnostic radiology ke liye AERB standard ke mutabik kam se kam 0.25 mm aur fluoroscopy me 0.5 mm lead equivalent apron zaroori hai.
Explanation: Fixer unexposed silver halide crystals ko dissolve karke film ko permanent aur light-insensitive banata hai.
Explanation: Ye photostimulable phosphor (PSP) plate latent image ko store karti hai jise red laser scan karke digital signal banata hai.
Explanation: Intensity distance ke square ke inversely proportional hoti hai ($I \propto 1/d^2$). Distance double karne par intensity 1/4th reh jaati hai.
Explanation: Waters view maxillary sinuses ko petrous ridges se upar project karta hai jisse sinusitis aur fluid levels clear dikhte hain.
Explanation: Occupational workers ke liye 5 saal me average 20 mSv/year (total 100 mSv) allowed hai, jabki public ke liye 1 mSv/year limit hai.
Explanation: Aluminium filter soft radiation (low energy rays) ko rok kar patient ki skin dose ko significantly kam karta hai.
Explanation: 7 Cervical, 12 Thoracic, 5 Lumbar, 5 Sacral (fused to 1) aur 4 Coccygeal (fused to 1) milkar 33 vertebrae banti hain.

Agar aap sochte hain ki x ray technician exam kaise pass karein, toh ye 4-step structured strategy aapko top merit list me la sakti hai:
Step 1: Radiation Physics ke Formula aur Principles Clear Karein
Inverse Square Law, kVp-mAs relationship, line focus principle, aur heat unit calculations ($HU = kVp \times mA \times s$) ke numericals ko ratne ki bajaye samjhein. Exam me sidhe concepts aur numericals par sawal aate hain.
Step 2: Skeletal Anatomy aur Radiographic Projections ko Visualize Karein
Bones ke exact anatomical landmarks (e.g., Greater Tubercle, ASIS, Mastoid tip, Foramen Magnum) ko diagrams ke sath yaad karein. Jab tak aapko positioning ke central ray (CR) angles pata nahi honge, tab tak clinical MCQs solve nahi honge.
Step 3: AERB Guidelines aur Safety Rules par Command Karein
TLD badge, dosimeter, lead glass, aur permissible annual radiation limits (20 mSv occupational, 1 mSv public) yaad karein. Ye section scoring hota hai aur isme negative marking ka risk sabse kam hota hai.
Step 4: Daily Online CBT Mock Test Lagayein
Sirf btsc x ray technician book ya theory notes padhna kaafi nahi hai. Online test lagane se time manage karne ki aadat banti hai aur computer par option tick karte waqt silly mistakes nahi hoti hain.
