In summary, if a radioactive sample of 59Fe (t1/2= 44.496 d) has an activity of 1000 disintegrations per minute, the weight of 59Fe present can be determined by using the given half-life and activity. The more massive the sample, the more disintegrations per minute there will be.

You are given the half-life and also how many disintegrations per minute are occurring with this sample. The more massive the sample, the more disintegrations per minute there will be...
What is the weight of a radioactive sample?
The weight of a radioactive sample can vary greatly depending on the type of radioactive material it contains. Some samples may weigh only a few grams, while others can weigh several pounds.
How is the weight of a radioactive sample measured?
The weight of a radioactive sample is typically measured using a scale that is sensitive enough to detect even small changes in weight. This allows scientists to accurately measure the weight of the sample and track any changes over time.
Why is it important to know the weight of a radioactive sample?
Knowing the weight of a radioactive sample is important for several reasons. It can help scientists determine the concentration of radioactive material in the sample, which is crucial for understanding its potential impact on the environment and human health. It can also be used to calculate the decay rate of the sample.
Can the weight of a radioactive sample change over time?
Yes, the weight of a radioactive sample can change over time due to the process of radioactive decay. As the atoms in the sample decay, they release energy in the form of radiation, which can cause the weight of the sample to decrease over time.
How can the weight of a radioactive sample be used to predict its decay rate?
The weight of a radioactive sample can be used to predict its decay rate by measuring the amount of radiation being emitted from the sample. As the weight decreases, the rate of radiation emitted also decreases, allowing scientists to estimate the half-life of the sample and its rate of decay.
