Match each property (1 to 3) with its unit of measurement. 1. activity 2. absorbed dose 3. biological damage a. rad

Verified step by step guidance

1. Identify the property 'activity' and recall that it is related to the rate of decay of radioactive substances, typically measured in units like becquerels (Bq) or curies (Ci).
2. Consider the property 'absorbed dose', which refers to the amount of radiation energy absorbed per unit mass of an object, commonly measured in units such as grays (Gy) or rads.
3. Recognize that 'biological damage' is associated with the effect of radiation on living tissue, often measured in units like sieverts (Sv) or rems, which take into account the type of radiation and its impact on biological tissue.
4. Match the property 'absorbed dose' with the unit 'rad', as 'rad' is a traditional unit for measuring absorbed dose.
5. Conclude that the unit 'rad' is specifically associated with the property 'absorbed dose', while 'activity' and 'biological damage' are measured in different units.

Key Concepts

Activity

Activity refers to the rate at which a radioactive substance decays, typically measured in units such as becquerels (Bq) or curies (Ci). It quantifies the number of disintegrations per second, indicating how much radiation is being emitted by a sample. Understanding activity is crucial for assessing the potential exposure to radiation.

Absorbed Dose

Absorbed dose measures the amount of energy deposited by ionizing radiation in a given mass of tissue, expressed in grays (Gy) or rads. This concept is essential for evaluating the potential biological effects of radiation on human health, as it directly relates to the energy absorbed by the body.

Biological Damage

Biological damage refers to the harmful effects that radiation can have on living tissues, which can lead to cellular damage, mutations, or cancer. This concept is often assessed using units like sieverts (Sv) or rems, which take into account the type of radiation and its biological impact, making it vital for understanding the risks associated with radiation exposure.
