試題 :
1. Please list the measurement units for radioactivity. radiation exposure,
absorbed dose, and equivalent dose, respectively. Whar are the relationships
among absorbed dose, equivalent and effective dose. (10%)
2. Please briefly describe the basic types for ionizing radiation exposure
monitoring?
Please also describe the basic types of radiation detectors. Use two of
them as examples to illustrate the mechanisms for radiation detection.(20%)
3. Please introduce the system of dose limits(劑量限度體系) for ionizing
radiation exposure?
What dose Annual Limit of Intake mean? How is it defined? (10%)
4. Please briefly describe relative biological effect(RBE) and linear energy
transfer(LET), respectively. What is the relationship between them? (10%)
5. Please tell the differences among subradiofrequency, radiofrequency/micro-
wave, and optical radiation, in terms of frequency, energy, application,
health concerns. (15%)
6. What do far-field and near-field mean? What are their roles in the electric
and magnetic field measurement? (10%)
7. What precautions should be taken when conducting a measurement for sub-
radiofrequency field strength? (in terms of measurement type, measurement
units, measurement tools and procedures) (10%)
8. In laser exposure standard setting, what principal parameters associated
with laser hazard severity should be considered?
In the ACGIH TLVs for visible and near IR, there is a category with
wavelength weighting in term of aphakic hazard function. What does it mean
and what is it for? (15%)
