Unstable nuclei decay. However, some nuclides decay faster than others. For example, radium and polonium, discovered by the Curies, decay faster than uranium. This means they have shorter lifetimes, producing a greater rate of decay. In this section we explore half-life and activity, the quantitative terms for lifetime and rate of decay. Why use a term like half-life rather than lifetime? The answer can be found by examining Figure 1, which shows how the number of radioactive nuclei in a sample decreases with time.
Half of the remaining nuclei decay in the next half-life. Further, half of that amount decays in the following half-life. If N is a large number, then many half-lives not just two pass before all of the nuclei decay. Nuclear decay is an example of a purely statistical process. Thus, if N is reasonably large, half of the original nuclei decay in a time of one half-life.

Because the types of HIV tests available are changing, and the window periods associated with these tests are getting shorter, counseling patients about the best time to test for HIV can be challenging. Balancing these priorities can be challenging for clinicians and difficult for patients to understand. The Table of Probabilities tool was designed to give the probability of a false negative test result if a patient has HIV.
Calculate the date that occurs exactly one hundred days from today, or include only business days or weekdays.
There are a number of different ways to calculate your due date, including:. Your due date is considered to be 40 weeks days after the first day of your last menstrual period or 38 weeks days after ovulation. Assuming you know the date of your last period, your primary care provider will use this to figure out the due date. Many midwives and obstetricians use a pregnancy wheel, which is a simple tool that quickly gives the th day from your last period.
There is a formula known as Naegele’s rule. This is what is used for the due date calculator at the top of this page. It’s also how a pregnancy wheel works. You can calculate the date yourself using Naegele’s rule. For example, if the first day of your last period was August 11, , you would:. If your fertility app gives you a different date than the one calculated by your doctor, it most likely because it was based on the ovulation date and not the date of your last period.
If you ovulated earlier or later than day 14 of your cycle, this would shift your due date accordingly. Your due date in relation to ovulation is considered to be more accurate than one calculated based on your last menstrual period.

Nuclear half-life expresses the time required for half of a sample to undergo radioactive decay. Exponential decay can be expressed mathematically like this:. So, if a problem asks you to calculate an element’s half-life, it must provide information about the initial mass, the quantity left after radioactive decay, and the time it took that sample to reach its post-decay value. Let’s say you have a radioactive isotope that undergoes radioactive decay.
It started from a mass of Here’s how you would determine its half-life:. Sometimes, if the numbers allow it, you can work backwards to determine an element’s half-life. Let’s say you started with g and ended up with 25 g after 1, years. One of the Nuclides in spent nuclear fuel is U, an alpha emitter with a half-life of 2. If a spent fuel assembly contains 5. Key Questions How can I calculate the half life of an element? Here’s how you would determine its half-life: Starting from 1 , we know that 0.
