stopping access to the controlled area.

Items to bring when health checking
Radiation handlingregistrant’s paper①Questionnaire(filled in)②Exposure measurement record(attached to the registrant's notebook)

During the interview, you will be asked about your healthcondition and the status of radiation handling.

Measurement of
individual exposure
dose (Article 39)

P9

The measurement results of individual exposure doses arepermanently stored.
（１）Measurement of external exposure
Man (chest) Woman (belly):
Continuous measurement while entering the controlled area
If you do not have a radiation measuring instrument, you will be prohibitedfrom entering the controlled area.

（２）Measurement of internal exposure* If there is internal exposure, the radiation facility will notify you.
When there is no notification, the external exposure measurement result
itself will be your personal exposure dose.

Measurement of
individual exposure
dose (Article 39)●Measuring instruments: glass badges,

pocket dosimeters, etc.
→Exchange every month
Be sure to return it at the end of the month●Measurement period: While entering the controlled area
●Measurement report: Distributed monthly(only for those who enter the controlled area)

Check for exposure and attach to the handler's notebook
Normal handling: X detection limit (<0.1mSv)（Reference）Effective dose limit

Treatment of inorganic fluid waste〇The waste liquid is stored and discarded in a predetermined
container at least up to the first washing water.
―Wastewater that exceeds the wastewater concentration limit
cannot be drained.

〇If it is sorted by nuclide, follow it.
The pH is adjusted to 2-12.
―Ammonia or sodium hydroxide, acetic acid or sulfuric acid is recommended
as the pH adjustment reagent.
―Dilute or dissolve the reagent before use so that the neutralization reaction
does not become violent.
―Do not use reagents that contain chlorine.

Sample processing after use• Samples that you do not want to discard due to re-experiment will be stored as branched products in thestorage room, so follow the instructions of theStorageroomadministrator.

• Do not leave the contaminated chips and gloves usedin the RI experiment in the laboratory and dispose ofthem immediately.
• Even if it is less than the minimum quantity of the law(even if it is attenuated), it cannot be taken out of thecontrolled area.

Emergency Response Rules（１）Maintaining safety
Human life and physical safety are considered first, and damage
to property is second. Lifesaving takes precedence overeverything.

（２）Notice
Promptly notify nearby persons and radiation control personnel.
① Accident occurrence time and place② Types of accidents (exposure, pollution, fire, explosion, etc.)③ The situation (whether there are casualties, whether there isexpandability, etc.)④ Your name, affiliation, phone number, etc.

Emergency Response Rules（３）Prevention of pollution spread①Take measures to prevent expansion.
② Elimination of the cause of contamination,
sealing of contaminated areas, prevention ofcontamination leakage• Raise the fallen container.
• Place an absorbent or vinyl cloth on the spilled RI.
• Make a seal on the door.
• Stop the damper.

Places where pollution is likely
to occur• I centrifuged the microtubes without noticing that they were
contaminated.

– When inserting RI into the microtube with a pipettor, the tip of the tip
touched the lid.
– The lid became contaminated as the cap was repeatedly opened andclosed.
– There was too much internal solution and it was contaminated withpressure when the cap was closed.

If you centrifuge it while it iscontaminated ...

The entire inner wall of the rotor andcentrifuge is contaminated.
Decontamination after disassemblyPlaces where pollution is likely
to occur• When stirring the solution with avortex mixer, cover it while
holding the center of the test
tube so that the solution does not
rise to the top of the test tube.
* If you hold the upper side, theliquid will rise and the lid will becontaminated.

handling• Contamination cannot be measured

with a survey meter for 3H, 14C, and35S.
• To experiment smoothly without
spreading pollution ...
– Change gloves and wash your hands(be careful of "drops" when washingyour hands)– Put on rubber gloves on the surgicalgloves and change only the rubber
gloves frequently.
– If you double the gloves, you don't haveto worry about sudden damage to thegloves.

handling• To experiment smoothly without spreading
pollution ...

– Use of polyethylene filter paper that changes
color when liquid adheres– After using a pipette or tip, liquid remains, so
absorb it with a paper towel to remove them.

Amendment of campus rules
１． Radioactive （2013.3.28、2013.6）
contaminants
Definition of radioactive material

２． Report to Nuclear Regulation Authority
３． Inspection of radioactive isotopes that are notunder control

Our staff must inspect and report to the President
when hiring, relocating or retiring.

４． Addition of emergency reports

Unplanned exposure (effective dose of 5 mSv ormore), etc.

５． Other terms, etc.

Acceptance / delivery, shielding of radioactive
isotopes, etc.

Amendment of campus rules （2005.12.22）

１． Added provisions for out-of-control use of unsealed RIs.
At this time, there are no facilities that can be taken out toKumamoto University because permission from the Ministry of
Education, Culture, Sports, Science and Technology is required.

⇒ It is prohibited to take it out now!
２． A regular training system for radiation handling chiefs

has been added.
３． Division into Radiation workers and the surveillance area
workers.
４． Electron microscope less than 100kV：Excluded from regulation.
ECD gas chromatograph with display：It became an Approved Devices with Certification
Labels and it can be used even if you are not aradiation handler.
