Master File

Which one from the following is the possible result of radiation exposure on the cell?
The cells are able to completely repair any damage and function normally.
The cell is damaged but is still able to reproduce.
Cell dies from the damage
All of above
Definition of Anoxic cells
Cells with insufficient oxygen
Cells tend to reproduce rapidly
Cells with a good blood supply
Cells shrink in size
True or false:
Low doses tend to kill cells ( )
High doses tend to damage or change ( )
High doses of radiation over short periods of time producing acute or short term effects ( )
Low doses of radiation over an extended period of time producing chronic or long term effects ( )

The least sensitive organ post radiation exposure is
Gastrointestinal system
Brain and muscles
Lymphatic system
Blood forming organ
Carcinogenic effect is the
Mutation of the reproductive cells passed on to the offspring of the exposed individual
Effect is suffered by the individual exposed
Effects of radiation on embryo
Effect of radiation on blood forming organ
A relatively inexpensive, lightweight, Survey instrument detector is a
Scintillation Counting
Thermoluminescent dosimeters (TLD)

True or False ,The proper response to large amount of spill
Clean up the spill using disposable gloves and absorbent paper. Carefully fold the absorbent paper with the clean side out and place it in a plastic bag for transfer to a radioactive waste
Container ( )

Report the spill to the PI ( )
Survey the area around the spill, your hands, clothing, and shoes for contamination.Wash contaminated skin. All personnel contamination (e.g. shoes, skin, clothing ( )
limit the movement of all personnel who may be contaminated

TheHealth Physics presence is required whenever there is
If the dose rate is greater than 100 mrem per hour
If the dose rate is less than 100 mrem per hour
If the dose rate is below or equal to 5 mrem per hour at 30 cm from the shield surface
If the dose rate < 5 mrem/hour at one meter
Radioactive waste is
A useless radioactive material
A leftover material after laboratory process is accomplished
A useful radioactive material after recycle

Definition of radioactive contamination
A presence of radioactive material that been absorbed and stain your lab coat
A presence of a radioactive material in undesired place
An infection passes from person to another person
Hazardous waste
Unwanted chemical materials product that have risk to environment
A non‐medicalwaste combined with radioactive waste
A waste that contains radioactivity and chemical wastes

Dish detergent, window cleaner, vinegar, bubble bath, waterless hand cleaner are suitable product for cleaning surface contamination. ( )
All waste containers mustnot be labeled with the radiation symbol and a sign reading “Caution—Radioactive Materials. ( )
Contaminated equipment should not be placed in a Dry Waste Box( )
Place only dry, nondecomposablewastes such as gloves, paper, and
Glassware in Dry Waste Boxes ( )

Safe disposal of radioactive waste is inexpensive( )

The bioassay requirement
In case of handling more than 100 millicuries of tritium, you are required to submit a urine sample to Health Physics 7 to 14 days after the experiment
Individuals who handle large amounts of volatile radionuclides may be required to participate in a bioassay monitoring program
The thyroid measurement should be within 72 hours following exposure
All of the above

The purpose of personnel monitoring is
to provide early notice if your exposure is not below the limits and

to provides a permanent record of your exposure
none of the above
all of above
Finger rings can be worn
In any party
In highly exposure places
In the office
Missing dosimeter will affects the monitoring program’s ability to Provide accurate exposure readings ( )
Rings are to measure hand exposures only. ( )
TLDs are most often worn by persons exposed to a variety of isotopes such as found in nuclear medicine or the cyclotron facility( )
Film badges are most often worn by all hospital staff ( )
All dosimeters are processed by a contractor. They are collected in the first week of every year( )

17.Signs and labels provide hazard information and warnings to

Elementary school students
Co‐workers, support staff, and emergency responders

Device calibration records should be performed by
Health Physics, repair companies, and
Laboratory staff

19.Cabinet x‐ray machine

Should be decorated in harmony with the place
Should be securely closed, self‐shielded andinterlocked
Should be operated even if the cabinet is not locked
Radioisotope Journal must be accessible to all persons who work with radiation sources and must be available for inspection at any time( )
The work area should provide sufficient space for supplies, work,
And waste ( )

Storage or consumption of food or beverage in any laboratory work area is strongly courage( )
The desk area must be posted with an orange notice reading

During the inspection, Deficiencies that are occasionally observed include
Evidence of food or beverages in laboratory work areas or
Inadequate attention to work rules

Complete room surveys
Adequate security of radioactive material
Lack of on‐the‐job training
A & D
B & C
None of the above

22.Suspensions of work is not necessary

due to overexposure
due to underexposure
injury to personnel
multiple or uncorrected deficiencies
The role of Radiation measurement and safety equipment survey is
to determine which instruments are appropriate
to check which instrument is shared
To check the heavy equipment if its shielded for earthquakes
All of above
Spontaneous emission of charged particles or photons by an atomic nucleus that is in an unstable configuration is called radioactivity( )
The alpha particle is simply a helium nucleus, comprised of two protons and one neutron( )
The beta particle is an electron that has been ejected from a neutron‐richnucleus( )
A positron is the anti‐particle of a beta particle, is emitted by a proton‐rich nucleus( )
A high energy photon emitted by a nucleus during its transition from a higher energy
Excited state to a lower energy unexcited state is

Gamma ray
Isomeric transition
Internal conversion
