Requires Netscape 3.0, Internet Explorer 3.0 or higher. JavaScript must be enabled.
For educational purposes only. No warranty.
For optional viewing of the results in chart form, Netscape 4.0, Internet Explorer 4.0 or higher is required, and Java must be enabled (uses Java applet KavaChart external link).

Calculate activities and radioactive decay of the wastes arising from nuclear fuel production and power plant operation: uranium mine waste rock, uranium mill tailings, depleted uranium, and spent fuel.

Enter a value into any one field of the Material Balance and click the "Calculate" button below. HELP new window
Numbers can be entered in exponential notation: 5 · 10-6 = 5e-6
"t" means metric tonne.
