A library to model nuclear physics in javascript. Intended for building visualizations and interactive demonstrations.
Get the decay products for the given isotope. The isotope parameter is a compact name like Pu-239.
radioactive.decay.products('Pu-239');returns an array of products produced in the decay process:
[
{
fraction : 1, // in the range [0, 1]
product : 'U-235' // a compact isotope name
},
...
]Get the complete decay chain for the given isotope. The isotope parameter is a compact name like Y-99.
radioactive.decay.chain('Y-99');returns an array of products produced in the decay process:
["Y-99", "Zr-99", "Nb-99m", "Nb-99", "Mo-99m2", "Mo-99m1", "Mo-99", "Tc-99m", "Tc-99"]Get a decay profile of isotope mass for a starting charge of isotopes. The charge parameter is a dictionary of compact isotope names (like `Pu-239') to initial charges (kilograms) of that isotope.
radioactive.decay.mass({
'Y-99' : 1 //kilograms
});returns a function that can be passed time in years. That function will return a dictionary of isotope masses remaining at that time:
{
'Y-99' : 0.02, // kilograms
'Zr-99' : 0.8, // kilograms
...other isotopes...
'total : 1 // kilograms
}Get a decay profile of radioactivity for a starting charge of isotopes. The charge parameter is a dictionary of compact isotope names (like `Pu-239') to initial charges (kilograms) of that isotope.
radioactive.decay.radioactivity({
'Y-99' : 1 //kilograms
});returns a function that can be passed time in years. That function will return a dictionary of isotope masses remaining at that time:
{
'Y-99' : 5510123, // becquerels
...other isotopes...
'total : 14310123 // becquerels
}This module isn't implemented yet. Simulating fission and neutron capture is a real-time process, and needs totally different math & datasets.
Things this module will need to know about
- Fission isotope spread
- Neutron absorption probabilities for different energies and istopes
- Energies and products released
- Geometry of the situation
- Accompanying thermal model would make it actually useful
Contributions are welcome!
