CT Scan Radiation Dose Kya Hota Hai? (mSv Explained Simply)

Introduction

Aaj ke time mein CT Scan ek bahut important medical test ban chuka hai. Lekin jab bhi CT Scan ka naam aata hai, log ek sawaal zaroor poochte hain –
“CT Scan mein radiation kitni hoti hai?”
Aur saath hi ek aur confusion hota hai – mSv kya hota hai?

Is blog mein hum radiation dose, mSv ka matlab, aur CT Scan kitna safe hai – sab kuch samjhenge.

Radiation Dose Kya Hoti Hai?

Radiation dose ka matlab hota hai human body ko kitni radiation mil rahi hai during any imaging test.

Medical imaging mein radiation dose ko millisievert (mSv) mein measure kiya jaata hai.

👉 Simple words mein:
mSv = body par radiation ka effect

---

mSv (Millisievert) Kya Hota Hai?

• Sievert (Sv) radiation ka unit hai

• Millisievert (mSv) = 1/1000 of Sievert

Medical field mein hamesha mSv ka use hota hai kyunki doses bahut kam hoti hain.

CT Scan Mein Kitni Radiation Hoti Hai?

Scan Type	Approx Radiation Dose
Chest X-ray	0.1 mSv
CT Head	2 mSv
CT Chest	6–7 mSv
CT Abdomen	8–10 mSv
Whole Body CT	10–20 mSv

👉 Important:
CT Scan ki radiation normal X-ray se zyada hoti hai, lekin controlled aur calculated hoti hai.

Daily Life Mein Radiation Exposure

Aap bina CT Scan ke bhi radiation le rahe hote ho:

• Natural background radiation (1 year) → 3 mSv

• Flight travel (India to USA) → 0.03–0.05 mSv

👉 Matlab radiation sirf CT Scan se hi nahi, nature se bhi milti hai.

CT Scan Safe Hai Ya Nahi?

✔ Yes, CT Scan safe hota hai jab:

• Doctor ne recommend kiya ho

• Proper protocol follow kiya jaata ho

• Modern CT machine ka use ho

❌ Unnecessary CT Scan avoid karna chahiye

Radiologist aur Radiographer hamesha ALARA principle follow karte hain:

ALARA Principle

A – As
L – Low
A – As
R – Reasonably
A – Achievable

Matlab jitni kam radiation mein kaam ho sake, utni hi di jaaye.

Radiation Dose Kam Kaise Rakhi Jaati Hai?

• Low dose CT protocols

• Automated dose modulation

• Patient size ke according settings

• Limited scan area

• Advanced CT technology

---

Patients Ko Kya Dhyan Rakhna Chahiye?

✔ Doctor se pooche CT kyun zaroori hai
✔ Purane CT/X-ray reports saath le jaaye
✔ Pregnancy ho to pehle bataaye
✔ Fear mein CT avoid na kare agar zaroori ho

Conclusion

CT Scan ki radiation controlled, measured aur safe limits mein hoti hai.
Jab CT Scan diagnosis ke liye zaroori hota hai, to uska benefit radiation risk se kaafi zyada hota hai.

📌 Yaad rakhiye:
👉 Right test at the right time = Safe & Accurate diagnosis
