Dose Estimator - Onset of Vomiting

1. Date/time exposure began calendar
(e.g., 01/22/2008 14:25)
2. Date/time vomiting began calendar

 
Dose Estimate
Gy
  • The new international system (SI) unit of radiation dose, expressed as absorbed energy per unit mass of tissue.
  • The SI unit "gray" has replaced the older "rad" designation.
  • 1 Gy = 1 Joule/kilogram = 100 rad.
  • Gray can be used for any type of radiation (e.g., alpha, beta, neutron, gamma), but it does not describe the biological effects of different radiations.
  • Biological effects of radiation are measured in units of "sievert" (or the older designation "rem").
  • Sievert is calculated as follows: gray multiplied by the "radiation weighting factor" (also known as the "quality factor") associated with a specific type of radiation.
95% confidence limits
If a population of people had the same time to onset of vomiting you entered into the tool, you would have 95% confidence that mean value for radiation dose received by that population would between the upper and lower value noted.

Note: Remember that in a mass casualty incident, vomiting may be related to many conditions other than radiation exposure, including psychological factors.
