**Quiz Question: Measuring Biologically Effective Radiation Dose**

**Question:**
Which of the following is a unit used for measuring the biologically effective radiation dose that will cause tissue damage to an organism?

**Options:**
1. ☉ Radiation absorbed dose (rad)
2. ☐ Curies (Ci)
3. ☐ Becquerels (Bq)
4. ☐ Grays (Gy)
5. ☐ Sieverts (Sv) or roentgen equivalents for man (Rem)

### Explanation:

This question is designed to test your knowledge of units used in radiation measurement. Each option represents a different unit employed in the field of radiology and radiological protection:

1. **Radiation absorbed dose (rad)**:
   - Traditional unit used to measure the amount of energy absorbed by a material from radiation.
2. **Curies (Ci)**:
   - Unit used to describe the activity of radioactive substances.
3. **Becquerels (Bq)**:
   - SI unit for radioactive decay, defined as one disintegration per second.
4. **Grays (Gy)**:
   - SI unit used to quantify the absorption of radiation dose.
5. **Sieverts (Sv) or roentgen equivalents for man (Rem)**:
   - Units used to reflect both the amount of radiation absorbed and the biological effect of that radiation on human tissue. This is the correct answer for the unit measuring biologically effective radiation dose.

### Correct Answer:
- ☉ Sieverts (Sv) or roentgen equivalents for man (Rem)
