Dental Xray

Had some pictures taken by a real tech at a dentist's office. I say real because when I asked the opener shot, she jaw dropped at me and said "I don't know." But, while the files were loading onto the laptop, she went and checked the equipment and said it was 0.05ųSv. Since she did her schooling back in the 90s, she didn't know what the unit was. I told her it was 5mR and made her day.
She said that as soon as I had asked the question she knew she better have a good answer, figuring that I probably already knew the correct response.😅

Obviously the time frame of ones schooling is irrelevant. 0.05usv does not equal 5mr. 0.05usv does equal 5ur.
0.05usv x 100ur/1usv x 1mr/1000ur = 0.005mr x 1000 = 5ur.
The poor girl had her day made with bogus information.

The dose of living in a brick house reminds me of a baseline survey we performed at a new construction power plant. The highest readings were the red brick guard house where the portal monitors were located.
