D = d x t
D = radiation dose
d = radiation dose rate
t = time duration of exposure
Inverse Square Law
D1 s12 = D2 s 22
D1 = dose at distance 1
s1 = distance 1
D2 = dose at distance 2
s 2 = distance 2
- energy of radiation
- type of shielding
There must be a warning light that illuminates when the x-ray tube is on. This light is adjacent to the x-ray tube or housing or port.

Laser Pointers Tips
General Laser Safety Precautions
The principal danger from lasers is to the eye. The primary region of concern for low power visible lasers is the retina of the eye.
What should I do if I am flashed in the eyes with a laser pointer?
As soon as you are aware of the laser, look away from the laser beam or close your eyes, and move out of its way.
If you become contaminated; you can take the following steps to limit the spread of the radioactive material.
1. Remove the outer layer of your clothing. If radioactive material is on your clothes, getting it away from you will reduce the external contamination and decrease the risk of internal contamination. It will also reduce the length of time that you are exposed to radiation.
2. If possible, place the clothing in a plastic bag. Keep people away from it to reduce their exposure to radiation. Keep cuts and abrasions covered when handling contaminated items to avoid getting radioactive material in them.
3. Wash all of the exposed parts of your body using lots of soap and lukewarm water to remove contamination. This process is called decontamination. Try to avoid spreading contamination to parts of the body that may not be contaminated, such as areas that were clothed.
