How is it possible to verify whether an ionization chamber does
not perturb
the radiation field in a water phantom? Support your explanation
with analytical expressions.
1- Describe how to charge from an ionization chamber is
converted to dose in water.
2- what condition is required for dose in a medium to equal
collision kerma.
Ionization Chamber region is used to detect high energetic ? and
? paricles while Proportinal region is suitable to detect ? and ?
particles with low energy. Why?
What are the disadvantages of using diode chamber for measuring
radiation
a. Angular dependent
b. SSD dependent
c. Energy dependent
d. Temperature dependent
e. Combination of Angular & Energy
Can radiation change our DNA? And if it does how does it
happen?
If certain enzymes were removed from a given system, how could
this affect a given body?
Verify that the Divergence Theorem is true for the vector field
F on the region E. Give the flux. F(x, y, z) = xyi + yzj + zxk, E
is the solid cylinder x2 + y2 ≤ 144, 0 ≤ z ≤ 4.
1a. How does the auditor verify the existence of assets such as
cash and inventory; liabilities such as notes payable?-Discuss How
would the auditor verify Completeness of sales revenue?-Discuss
1b. Discuss the concept of “reasonable assurance” and the degree
of confidence that financial statement users should have in the
financial statements?
how you will verify whether Bcell markers (including CD19,
CD20, and CD23) are down regulated with EBNA1 inhibitor treatment.
What assays do you want to do do verify this? How will you look at
this in the context of EBV gene expression and viral
load.
A thin-walled air ionization chamber whose volume is 0.5cm^3
collects a charge of 1.65 x 10^ -9 C when placed into a plastic
phantom whose relative mass stopping power is 1.1. When
manufactured, the ionization chamber was sealed when the
temperature was 25 degrees C and the atmospheric pressure was 770
mm Hg. What was the absorbed dose, in Gy and in rads, at the point
of measurement?
