Effective dose indicates the relative whole-body dose
for a specific exam and imaging modality, and not the dose for a patient.
The most commonly used biological dosimetry method is the cytogenetic technique, used mainly for whole-body dose
This results in a whole-body dose
to die patient of 350 mrem of radiation (iv), close to half the average U.S.
He said the amounts of plutonium that can cause cancer are measured in micrograms, and wouldn't necessarily show up when one measures a whole-body dose
. That is because there is a difference between radiation and the radioactive isotopes that cause cancers.
The effective dose also attempts to reflect the equivalent whole-body dose
, which results from actual absorbed dose to tissues that are irradiated during radiography or a computed tomography (CT) scan.
The scan results in a whole-body dose
of 18-30 mCi.
If the specific tissue dose is multiplied by the appropriate tissue weighting factor to obtain the equivalent whole-body dose
, then dividing the equivalent whole-body dose
by the tissue weighting factor should yield the specific tissue dose.
E is used to quantify the risk from partial-body exposure as opposed to that from an equivalent whole-body dose
. E is "the sum of the weighted equivalent doses in all tissues and organs of the body."
METHODS: For these vitamin D3 calculations, we used geometric conversion factors that change planar to whole-body doses
, which previous calculations did not incorporate.
Acute radiation sickness (hair loss, burns, skin redness) may develop after whole-body doses
above 1,000 millisieverts.
Because these treatments are whole-body doses
, it's impossible to localize the drug where it will do the most good and then provide the proper amount of medication.
around 1.5 miles from the explosions received whole-body doses
quite similar to those from a single [whole-body] CT scan," Brenner notes.
