Dose Calculator (DoseCalc) is a utility for rapid calculation of parameters associated with the use of radioisotopes. Common users include Nuclear Medicine Physicians and Technologists, researchers in biomedical imaging, workers in radiation and health safety, and industrial users of radioisotopes. The basic dose calculation tool has five editable fields:
1) the isotope,
2) the time that the amount of activity is initially measured
(the calibration time),
3) the amount initially measured (the calibration dose),
4) the time the radioisotope is used (the administration
5) the amount of radioactivity left when used (the
administration dose).
6) the volume (arbitrary units) of the calibration dose
7) the volume of the adminstration dose

The basic concept is to select the isotope, enter any three of the remaining fields and calculate the fourth. Touching the displayed value in any one of the five fields will bring up an appropriate keypad or picker to enter a new value. The other field values will then turn red (indicating they may no longer be valid) until the user touches one of the six calculation buttons (‘Cal Time’, ‘Cal Dose’, ‘Admin Time’, ‘Admin Dose’, 'Cal Vol' or 'admin Vol'). Changing the isotope value results in recalculation of the administration dose field as appropriate for the new half-life value associated with the selected isotope.

DoseCalc comes with the following isotopes defined: C-11, Co-57, Co-60, Cu-64, Ga-67, Ga68, F-18, Ge-68, H-3, Ho166, I-123, I-124, I-125, I-131, In-111, Lu177, Mo-99, N-13, O-15, P-32, Rb-82, Re186, Re188, Tc-94, Tc-99m, Tl-201, Xe-133, and Y-90. Future releases will add additional isotopes and give the user the ability to add isotope information of their own to the application. Version 2 adds the ability for the user to edit the isotope list.
