However, half-life gives the time taken for half the nuclei of a sample to decay and thus the activity of the sample to halve. This bundle includes 8 full lessons with associated resources plus my lesson overview and resources list for the topic (ones highlighted in blue for combined science). It is not possible to say which particular nucleus will decay next but given that there are so many of them, it is possible to say that a certain number will decay in a certain time. My lessons are comprehensive, well organised and promote high levels of pupil engagement. Stores and Transfers. Scientists can measure the half-lives of different isotopes accurately: Uranium-235 has a half-life of 704 million years, This means it would take 704 million years for the activity of a uranium-235 sample to decrease to half its original amount, So after 5700 years, there would be 50% of the original amount of carbon-14 remaining, After two half-lives, or 11 400 years, there would be just 25% of the carbon-14 remaining, With each half-life, the amount remaining, The time it takes for the activity of the sample to decrease from 100 % to 50 % is the half-life, It is the same length of time as it would take to decrease from 50 % activity to 25 % activity. Edexcel Physics (Updated 2019) - iGCSE Science Courses Although half-life is not affected by chemical and physical reactions, different isotopes have different values for half lives, which come with different hazards. These signals can be converted into clicking sounds, giving a count rate in clicks per second or per minute.

The illustration below shows how a radioactive sample is decaying over time: From the start of timing it takes two days for the activity to halve from 80 Bq down to 40 Bq. This is called the half-life. Mark Schemes. So one half-life is five days. The time it takes for the number of radioactive nuclei to quadruple. It takes another two days for the activity to halve again, this time from 40 Bq to 20 Bq. There are 13 more questions available in this topic.
