The unit used to measure the biological effect of radiation sample is called the sievert rad rem curie

The unit used to measure the biological effect of radiation is called the sievert (Sv). The sievert is the SI unit for radiation dose equivalent, which takes into account both the absorbed dose of radiation and the type of radiation involved. It is commonly used to quantify the potential health effects of radiation exposure.

The rad (radiation absorbed dose) and the rem (roentgen equivalent man) are older units for measuring radiation dose. The rad is a unit of absorbed radiation dose, while the rem is a unit of radiation dose equivalent. These units are not used as frequently as the sievert anymore, but they can still be encountered in some older literature or regulatory standards.

The curie (Ci) is a unit used to measure the activity of a radioactive substance. It is not a unit of biological effect or radiation dose, but rather a measure of how many radioactive decays occur per second in a given sample. The curie is not directly related to the biological effects of radiation exposure.

The unit used to measure the biological effect of radiation is called the sievert (Sv). It is a derived unit in the International System of Units (SI) that quantifies the radiation dose equivalent to the biological effect on human tissues. It takes into account the type of radiation and its relative biological effectiveness.

The rad (Radiation Absorbed Dose) and rem (Roentgen Equivalent Man) are older units that were used to measure radiation exposure. The rad measures the amount of energy absorbed per unit mass of tissue, while the rem quantifies the biological effect of radiation by incorporating the type of radiation and its potential damage to human tissues.

The curie (Ci) is a unit used to measure the activity of a radioactive substance. It indicates the rate of decay of radioactive material. It is not directly related to measuring the biological effect of radiation but rather the quantity of radioactive material present.

In summary, the sievert (Sv) is the unit used to measure the biological effect of radiation, whereas the rad, rem, and curie are units related to radiation exposure and radioactive decay.
