Dosimetry is the science of measuring the deposited radiation energy, or radiation dose, resulting from the exposure to an ionizing radiation source, such as an x-ray machine or a radioactive source. A personal dosimeter is a device used to measure the accumulated radiation dose in human tissue. Workers who may be exposed to radiation routinely carry personal dosimeters.

Before the invention of the instadose™ dosimeter, radiation workers' only option would be to wear a dosimeter for a period of time and send it in for processing to find out their accumulated dose for the wear period. With instadose, users can determine their accumulated dose instantly at any time by plugging the device into the USB port of any computer with internet access.

Why Is It Important to Wear a Dosimeter? Wearing a dosimeter on a daily basis is important to the health and safety of employees who work in radiation environments. The only way to determine an employee's real accumulated dose level is to have them wear a dosimeter every day and to check their dose reports regularly. Increased exposure to radiation can potentially increase the risk of illness. Therefore, monitoring your employees' accumulated radiation dose over time is important. This will ensure that they will not experience any significant health risk due to radiation. In the rare case where an x-ray machine malfunctions or there is an error during a procedure, unacceptably high levels of exposure to radiation can be detected early before any significant danger occurs. By using a dosimeter device in your practice you can:

• Confirm safety procedures are being followed.
• Detect faulty equipment or gaps in safety practices.
• Monitor pregnant workers.
