'Calculate' button, and the resultant answer is automatically calculated and shown.ДЄ 10mg drug has been administered to a patient. Entering in the initial amount of the substance is optional. To use this calculator, a user simply enters in the half life and the time that has transpired.

So calculating half lives is very important for many reasons, ranging from radioactive materials to drug use. Toxicity levels, because it lasts longer in the body therefore, if a person keeps taking more and more of it (being that it has a longer half life, it remains in the body longer), dangerous levels Drugs with longer half lives are at higher risk for abuse and dangerous So that it can be known how often a person can take dosages of drugs, to avoid building up a toxic drug level in the body. Drugs are notorious for having half lives, because it has to be known how long a drug will stay in the human body. Then another 6 hours another half will be consumed, leavingДў.5mg remaining in the person's body after 12 hours has transpired. This means that 6 hours later, half of the medication will be consumed, leaving half remaining, at 5mg. The half life calculator can be used to calculate the remaining amount of anything such as radioactive decay or for drug calculations. The exception that the initial amount of the substance, N 0, is removed from the formula.

Basically it's the same as the last formula with If a user doesn't enter in an initial amount, the formula which calculates the half life is, N(t)= e -t ln(2)/t 1/2. This is why the half life curve descends in value exponentially as time goes by. The e function is raised to a negative value, which means that is exponential decline in value. The formula calculates the remaining amount based t 1/2 stands for the half life of the substance. The substance (before the time has elapsed). If a user enters in an initial amount, the formula which calculates the half life is, N(t)= N 0e -t ln(2)/t 1/2. In the initial amount of the substance, then the calculator calculates the amount of the substance that remains in the units entered. The time has transpired), then the calculator will compute the fractional (decimal) portion of the number that remains of the original amount (after the time has transpired). If the user doesn't enter in the initial amount of the substance (the amount before With this half life calculator, the user has the option of entering in an initial amount or not. Today it is being replaced by electron beam radiation therapy systems.The half life calculator is calculates the remaining amount of a substance based on the half life of the substance and the time that has elapsed. When it decays to stable nickel, it emits two relatively high-energy gamma rays. In the medical field, the radioactive isotope Cobalt 60 has been used for radiotherapy to shrink tumors that will later be surgically removed, or to destroy cancer cells in inoperable tumors. Since half life is a constant, the ratio of carbon 14 to nitrogen 14 provides a measurement of the age of a sample. At the time of death organisms stop producing carbon 14. During beta decay, carbon 14 becomes nitrogen 14. It measures the time it takes for a given amount of the substance to become reduced by half as a consequence of decay, and therefore, the emission of radiation.ДЄrcheologists and geologists use half-life to date the age of organic objects in a process known as carbon dating. The half-life of a radioactive substance is a characteristic constant. It's a Question of Physics: What is meant by half-life? Half-Life
