- About what percentage of somatic damage from radiation is reparable, however, the remaining 10% becomes cumulative with repeated exposures to radiation
- ___ mGy for decreased blood cell counts (for total body)
- Lowest radiation dose resulting in any measurable biological effect is about ___ mGy, which can cause visible chromosome aberrations.
- Defined as those manifested within hours, days or a few weeks after radiation exposure, (whereas late effects occur in several months or years) is what type of effects
- ____ risk = number of case / million / year
- Increase in probability with increasing dose (no threshold), while the severity is independent of dose level; an all or none response
- ____ effects caused by radiation exposure to the developing embryo or fetus are deterministic
- ___ mGy for 50% loss of lymphocytes (for total body)
- Spermatazoa have a 3-5 week maturation period, already mature cells are radioresistant
- During pregnancy, ____ effects caused by radiation exposure to gametes prior to conception are stochastic effects
- Which of the following processes is Epithelial to Mesenchymal Transition observed?
- It is primarily the ___ effects of radiation that we are concerned with in the diagnostic radiology department
- Most late effects of radiation are stochastic, including most carcinogenic (cancers) effects, and most genetic (hereditary) effects follow what type of response curve?
- Deterministic effects are considered ____ to occur to the exposed individual, provided the threshold dose has been reached
- The best information is obtained when ___ or ___ of these methods can be applied and agree
- What effects may occur at low dose levels, such as those encountered in routine diagnostic radiography
- Stochastic effects are ___, measured statistically within a population
- ____ risk = number of cases beyond the normal expected in a particular group
- Increase the severity with increasing dose above a threshold dose (due to an increased number of cells damage)
