| What are two types of biologic damage that can occur due to overexsposure? |
|
Definition
- Somatic- damage done to body within lifetime
- Genetic- damage or injury to genes
|
|
|
Term

|
Definition
- Absorbed dose
- Dose equivalent
|
|
|
Term
| What is the unit of absorbed dose |
|
Definition
| Gray(Gy) which replaces the previously used unit rad (1 Gy=100 rad) |
|
|
Term
| The unit of dose equivalent |
|
Definition
| Sievert which supersedes the rem which was previously used (1 Sv=100 rem) |

Term
| State and Federal Restrictions dictate that occupationally exposed individuals older than 18 years of age and wearing monitoring devices can receive up to how much exposure? |
|
Definition
0.05 Sv/year
Remember: Nonoccupationally exposed persons can recieve 10% of this figure (0.005 Sv/year) |
|
|
Term
| Consists of a plastic holder that contains a radiation-sensitive film in a lightproof package, which is sensitive to beta, gamma and x radiation. |
|
Definition
Film badge
Remember:This is the most common monitoring device |
|
|
Term
| This monioring device is the same size and shape as a pen and fits conveniently in the wearer's pocket. It consists of an ion chamber and an electrometer. |
|
Definition
Pocket Ionization Chamber
Remember: The chamber is charged before use, and subsequent radiation discharges the ions. |
|
|
Term
| Contains special compounds(Lithium Fluoride and Calcium Fluoride) that are electrically altered by ionizing radiation and are sent back after a period of time for heat exposure which when heated emit light directly proportional to the amount of radiation they have absorbed. |
|
Definition

Note: Currently, film badges cost approximately 25% less than TLD badges. |
|
|
Term
| Why would you want to avoid retakes? |
|
Definition
| Reduce exposure to patient and personnel, saves time and money |
