Regression of points to straight line, correlation coefficient

Finding of natural divisors

The highest common divisor

Quadratic equation

Time difference

Estimation of some human biometric parameters

Concentration conversion

Simple radioactive decay (1 radioactive nuclide: A → B)

Successive radioactive decay (2 radioactive nuclides: A → B → C)

Successive radioactive decay (3 radioactive nuclides: A → B → C → D)

Conversion of activity units (traditional into SI-derived and vice versa)

Conversion of mass into activity and vice versa (mass-units into activity-units and vice versa)

(1.) Calculation of thyroid volumen on the basis of the lobes diameters

(2.) Calculation of (radio)nuclide uptake (f.e. uptake of radioiodine in the thyroid)

(2a.) Calculation of uptake of I-131 in the thyroid (This program can be saved as a file and launched in another PC, a browser with HTML and

(3.) Calculation of radioiodine dose (simplified)

(4.) Kinetic modeling I. (effective half-time, maximal uptake and others, based on a series of measures) - for radionuclide therapy

(5.) Kinetic modeling II. (effective half-time, maximal uptake and others, based on three measures) - for radionuclide therapy

(6.) Calculation of dose of radioiodine or another radionuclide for treatment (modified Marinelli-formula)

(7.) Dosimetry of α- and β-radiation

(8.) Dose rate and absorbed dose of γ radiation (in a distance from a point source)

The algorithm calculates the time difference between two time points. These points must be between the years 1970-2038. One year equals to 365.256 days.

The program was developed mainly for the calculations related to radioactive decay - see the options related
