Radiation

Question 1

Lymphocyte count for severe exposure

Answer 1

500-1000
100-500 is very severe

Question 2

Lymphocyte count for moderate exposure

Answer 2

1000-1500

Question 3

Lymphocyte count for lethal exposure

Answer 3

Less than 100

Question 4

100-200 rads exposure

Answer 4

n/v in 2-4 hours
no chance in lymph count

Question 5

200-600 rad exposure

Answer 5

n/v within 1 hour
lymph count < 1k at 24 hours
Impairment of routine tasks for >24 hours

Question 6

600-3000 rad exposure

Answer 6

n/v within 1 hour
lymph count decreases within hours
rapid incapacitation

Question 7

Neutrophil count in react diagram

Answer 7

Spike increase in prodromal phase (2 days
Drops at latent and bone marrow suppression phase (10 and 30 days)
Recovers in recovery phase (50 days)

Question 8

Platelet count in react diagram

Answer 8

Starts decreasing at later phase (10 days)
Peaks at bone marrow suppression phase (30 days)
Recovers at recover phase (50 days)

Question 9

Lymphocyte count in react diagram

Answer 9

Decreases at prodromal phase (within 2 days)
Slowly recovers by down marrow suppression phase

Question 10

Hemoglobin in react diagram

Answer 10

Slow decline until 40 days then recover
Smallest impact

Question 11

Guidelines for activity in radioactive zones

Answer 11

5 rem - all activities
10 rem - protect major property, save lives, protect large populations
20 rem - only saving lives/protecting large populations

Question 12

CNS impairment begins at what dose

Answer 12

200-600 rads

Question 13

Lymphocyte count of moderate radiation injury

Answer 13

1000-1500

Question 14

Lymphocyte count for severe injury

Answer 14

500-1000

Question 15

Lymphocyte count for very severe injury

Answer 15

100-500

Question 16

Lymphocyte count for fatal injury

Answer 16

Less than 100
