Converting from Roentgen (R) to Rad (rd) | Radiation

What is Roentgen (R)

Roentgen (R) is a unit of measurement for ionizing radiation that quantifies the ability of radiation to ionize air. It is commonly used to measure exposure to X-rays and gamma rays.

What is Rad (rd)

Rad (rd) is a unit of absorbed radiation dose. It measures the amount of energy absorbed per unit mass of tissue and is used to assess the potential biological effects of radiation exposure.

Conversion Formulas

The conversion between Roentgen (R) and Rad (rd) can be calculated using the following formulas:

• To convert Roentgen to Rad: Rad=1.15×R

• To convert Rad to Roentgen: R=0.8695652×Rad

Examples

1. Convert 11 Roentgen (R) to Rad (rd):

11 R=11×1.15=12.65 rd

2. Convert 4 Rad (rd) to Roentgen (R):

4 rd=4×0.8695652=3.478261 R
