Where IA is the change in absorbance at I>>max, b is the optical path length (cm), Iu is the molar extinction coefficient at I>>max (L mol-1 cm-1), I is the density of the dosimeter
(g.cm-3) and D is the absorbed dose (Gy).

For comparison to the alanine pellet dosimeter
influence quantities study, two sets of four alanine film dosimeters
were irradiated under identical conditions to doses of 10 kGy, 20 kGy, and 30 kGy.

Preliminary feasibility study of congo red dye as a secondary dosimeter
. Radiat Meas doi:10.1016/j.radmeas.
A chemical dosimeter
is a material which undergoes a measureable chemical change that can be calibrated to a known radiation source.
The development of the self-indicating instant radiation alert dosimeter
(SIRAD) is a vital addition to previously existing technology, greatly expanding affordability and accessibility.
This dosimetry system consists of a Panasonic model UD-802AS dosimeter
in a model UD-874AT holder and a model 710 reader.
(12) If patient dose is estimated during fluoroscopy, it is typically done using a dosimeter
to measure radiation exposure rate at the tabletop.
Routine treatment time as little as 3 min; less with undiluted albuterol; 1-2 mins for methacholine without a dosimeter
. New--the Asthma Rescue Kit for ER & ICU, incorporating the Medicator with a 90 mL continuous nebulizer & reservoir bag, will provide economical & standardized Heliox and/or bronchodilator therapy in a closed, low-flow, 0-resistance system w/ integral exhalation filtration and a portless mask.
