Cards

Term
cell membrane
Definition
In red blood cells, nerve cells the membrane distinguishes between sodium and potassium ions even though these ions are alike in size and electrical charge. ruptures at 3000-5000 rad
Term
cytoplasm
Definition
this material is an aqueous solution of soluble proteins and salts which constitutes the interior environment of the cell. least radiosensitive
Term
mitochondria
Definition
3000 rad. both plant and animal.
It is here that oxygen is used for oxidation of essential foodstuffs and formation of carbon dixoide.
Term
lysosomes
Definition
500-1000 rad. contain the digestive enzymes that break down large molecules, such as those of fats, proteins, and nucleic acids, into smaller constituents that can be the oxidative enzymes of the mitochondria.
Term
nucleus
Definition
brain of cell. most sensitive. In some cells this has a raletively fixed position and its found near the center
Term
law of bergone and tribondeau
Definition
cells most active in reproducing themselves and cells not fully mature will be most harmed by radiation.
Term
radiosensitive
Definition
germinal, hematopoietic,basal cells, epithelium
Term
radioresistant
Definition
bone, liver, kidney, cartilage, muscle, nervous tissue
Term
primary effect
Definition
ionazation
Term
secondary effect
Definition
products produced by free radicles
Term
stochastic effects
Definition
Any radiation could cause an effect.
2 effects cancer and cell mutation
Term
deterministic effects
Definition
10-25 rad. considered to result from the collective injury of a substantial number of cells in the tissue. skin burns,cataracts
Term
LD 50/30
Definition
50% of population in 30 days. happens at 450 rads
Term
somatic effects
Definition
to you personally. cancer, life span,cataracts
Term
acute effects
Definition
1.prodromal stage= nvd and loss of appetite
2. latent phase= no symptoms stand time
3.illness= ulcerations of mouth, fever, loss of hair
4.recovery or death= death is almost certain w the best medical care above 600 rad
Term
hematopoietic syndrome
Definition
200-1000 rad
reduction in white blood cells/nvd
Term
GTS
Gastrointestinal syndrome
Definition
1000-5000 rad survival is impossible. death occurs from both the damage to the lining of the GI tract (resulting in circulatory collapse) and damage to hematopietic system
Term
CNS
Central Nerve system
Definition
Swelling of brian. die w in 30 hrs
5000 rad
Term
Embryological effects
Definition
25 rad have been shown to be effective in producing development changes if applied during this time.
Term
heritable effects
Definition
what you pass on to your kids.
