Solving for initial number of nuclei

number of nuclei after time period (N) = 0 = 0 |

disintegration constant (K _{b})= 0 = 0 second^-1 |

time (t) = 0 = 0 second |

initial number of nuclei (N _{0})= NOT CALCULATED |

unit conversion factors

equivalent dose - SI unit is rem (roentgen equivalent man) - US unit is sievert | |

absorbed dose - SI unit is rad - US unit is gray | |

total radioactivity - SI unit is becquerel - US unit is curie |

Where

N | = | number of nuclei remaining after a time period |

N_{0} | = | initial number of nuclei |

K_{b} and K_{T} | = | disintegration constant |

t_{1/2} | = | half life time of radionuclide |

Q | = | total radioactivity or source strength |

N^{0} | = | Avogadro's number, 6.02 x 10^{23} atom/gram-atom |

W | = | atomic weight |
