Morning Cup O' Joe

Time you enjoy wasting isn't wasted time.

Ever wonder why X-ray Technologists always stay outside the room?

Well here’s why…

The following are comparisons of effective radiation dose with background radiation exposure for several radiological procedures.

mSv or milisievert is the SI derived unit of dose equivalent.

For this procedure:

Your effective radiation dose is: Comparable to natural background radiation for:
Abdominal region:
Computed Tomography (CT)-Abdomen

10 mSv

3 years

Computed Tomography (CT)-Body

10 mSv

3 years

Computed Tomography (CT)-Colonography

5 mSv

20 months

Intravenous Pyelogram (IVP)

1.6 mSv

6 months

Radiography-Lower GI Tract

4 mSv

16 months

Radiography-Upper GI Tract

2 mSv

8 months

Central Nervous system:
Computed Tomography (CT)-Head

2 mSv

8 months

Computed Tomography (CT)-Spine

10 mSv

3 years

Myelography

4 mSv

16 months

Chest:
Computed Tomography (CT)-Chest

8 mSv

3 years

Radiography-Chest

0.1 mSv

10 days

Children’s imaging:
Voiding Cystourethrogram

5-10 yr. old: 1.6 mSv

6 months

Infant: 0.8 mSv

3 months

Face and neck:
Computed Tomography (CT)-Sinuses

0.6 mSv

2 months

Heart:
Cardiac CT for Calcium Scoring

2 mSv

8 months

Men’s Imaging:
Bone Densitometry (DEXA)

0.01 mSv

1 day

Women’s Imaging:
Bone Densitometry (DEXA)

0.01 mSv

1 day

Galactography

0.7 mSv

3 months

Hysterosalpingography

1 mSv

4 months

Mammography

0.7 mSv

3 months

 

Concerned? =D

“The decision to have and X-ray Exam is a medical one, based on the likelihood of benefit from the exam and the potential risk from radiation….”

Basically in a nutshell… When your doctor orders an X-ray Exam for you, there’s a very good reason why.

Well here’s a little bit of Trivia:

If you were 1000 meters away from a nuclear explosion, you would receive and effective radiation dose of 4000mSv. That’s equivalent to over 1300 years worth of natural background radiation.

  1. The “sucks to be you” comment about Hiroshima is insensitive and out-of-place for this blog, dude.
