This screencast shows how to use the REMM web site Dose Estimator for Radiation Exposure,
an Interactive Tool. This is the tool. It has 3 biodosimetry options:
Time to Vomiting, Lymphocyte Depletion Kinetics, and the Dicentric Chromosome Assay
To use time to onset of vomiting tool,insert the date and time exposure began, insert the
date and time vomiting began, and click the Estimate Dose button
And then read the dose estimate in units of gray.
This tool may not be as accurate as others, but it may be the only one available initially
in a large mass casualty emergency. To use the Lymphocyte Depletion Kinetics tool,
insert the date and time radiation exposure began, the date and time the first CBC was
drawn, and the total absolute lymphocyte count, with special care to insert the value with
the correct decimal point. Then click Estimate dose from exposure.
The tool estimates a dose in units of gray. If multiple CBCs are drawn over a period of
hours to days, the dose estimate will be more accurate.
This tool allows input of up to 3 CBCs. The Dicentric Chromosome Assay is one of the
most accurate methods of estimating dose, but blood samples must be sent to one of the
few national reference laboratories, the results take days to process, and the throughput capacity
for the entire nation is small. So during the early phase of a mass casualty
event, this tool will not be able to help very many victims.
Before using any of the tools, be sure to read the Warning and Background sections for
details. This concludes the REMM web site screencast
about the Dose Estimator for Radiation Exposure, an Interactive Tool.
