• Quick start use the tips below to avoid manual filling of the input
• Examples already prepared runs to show the possible options
Hover on one of the examples to see how the fields are filled
Click to run the selected example
• Recall previous run keep track of what you already did
Previous run are memorized
Hover on one of the items to see how the fields were filled
Click to run the selected item
• Guide go through the details of the Medical Isotope Browser
• Product
Valid formats
99TC   TC99   99-TC   TC-99   TC 99   99 TC
Place the meta state in the near field as "M" or "G".

"show all" plots the activity of every produced nuclide, otherwise only the selected one and the sum of rest are plotted
• Target
Valid formats:
100MO   MO100   100-MO   MO-100   MO 100   100 MO  
Natural isotopic composition: input the element without mass (MO)

Custom composition
The "composition" button opens the input form (only for the element specified int Target field). Format
"mass" + " " + "value" (new line to add other masses)

The sum of the values can be any. Isotopia takes care of the normalisation
• Density
Leave the field blank to use the default value, which will be displayed in the output, or place your value
• Thickness / Exit energy


Thickness and Exit energy cannot be specified at the same time
• Energy range
An energy range is sampled.
One can choose to keep a fix Target Thickness or a fix Exit Energy .

The Exit energy and 3D buttons will be enabled:
Exit energy or Target thickness
as function of the Incident energy

a 3D plot of time, energy, and activity
• Cross section
Cross section
To input your own cross-section, press "User defined"




Input energy in Mev and cross section in mb, separated by a space, use point as decimal separator
Hover the mouse on the top-right on the plot. Dowloading, zooming, and other actions are available

Click on a legend item to hide/show the line.
Double click to isolate the line


Drag a rectangle to zoom on it. Double-click anywhere to restet the chart
Click on a line to access structure and decay data of the nuclide
Toggle linear / logarithmic y axis scale
Use this button to open the settings panel shown below
Choose the units you prefer
Remove from the plots the activities you might not need to display
Set the maximum target-product Z-distance
Set the maximum target-product A-distance
Where available the cross sections from IAEA-evaluated libraries (see below) are used. These are extended to the 0 - 200 MeV range using TENDL data
For reactions not covered by IAEA-evaluated cross sections, TENDL is used.
Each cross section used is labelled with the source library, and, in case of IAEA-evaluated ones, are also given the energies for which the TENDL library is being used to complete the 0 - 200 MeV range

IAEA cross sections
have been evaluated in a series of IAEA research projects that started in 2005. Numerical data and plots are available on-line at the IAEA Medical portal Medical portal
