What percent makes up our body
Organic molecules: 40% 50% 60%( 40%, 50%, 60% )
Water: 60% 40% 50%( 60%, 40%, 50% )

Direct Indirect( Direct, Indirect ) disturbance: the cell itself is affected
Indirect Direct( Indirect, Direct ) disturbance: the effect of radiation on water

G1: growth phase synthesis phase naturation phase( growth phase, synthesis phase, naturation phase )
S: synthesis phase growth phase naturation phase( synthesis phase, growth phase, naturation phase )
G2: naturation phase growth phase synthesis phase( naturation phase, growth phase, synthesis phase )

Naturation phase Growth phase Synthesis phase( Naturation phase, Growth phase, Synthesis phase ): structures synthesized readying for mitosis
Growth phase Synthesis phase Naturation phase( Growth phase, Synthesis phase, Naturation phase ): cellular contents duplicated except for chromosomes
Synthesis phase Naturation phase Growth( Synthesis phase, Naturation phase, Growth ): chromosomes start in here

Oxygenated tissue is more less( more, less ) sensitive to radiation effects than hypoxic tissue at lower higher( lower, higher ) energies

Law of Bergonie and Tribondeau:
The radiosensitivity of cells is directly inversely( directly, inversely ) proportional to their reproductive activity and inversely directly( inversely, directly ) proportional to their degree of differentiation

As LET increases, the potential for biologic damage increases decreases( increases, decreases )

What are the thresholds for the three syndromes of ARS?
Gastrointestinal: 10-50gy 2-10gy 50gy( 10-50gy, 2-10gy, 50gy )
Hematopoietic: 2-10gy 50gy 10-50gy( 2-10gy, 50gy, 10-50gy )
Central nervous: 50gy 2-10gy 10-50gy( 50gy, 2-10gy, 10-50gy )
