THE BASIC RADIOLOGICAL PROTECTION PRINCIPLES THAT SHOULD BE APPLIED IN THE EVENT OF A MAJOR ACCIDENT ARE GIVEN IN THE REPORT, AND ARE DEVELOPED INTO PRACTICAL ADVICE. SOME OF THE COUNTERMEASURES, AS WASHING FOODSTUFFS, WOULD BE RELATIVELY EASY TO IMPLEMENT.

SUCH

EMERGENCY

TO ENSURE THAT HONG KONG IS PROMPTLY INFORMED OF ANY AT THE DAYA BAY STATION, IRRESPECTIVE OF WHETHER OR NOT THE INCIDENT WAS LIKELY TO PHYSICALLY AFFECT HONG KONG, THE CONSULTANTS RECOMMEND THAT AGREEMENT SHOULD BE REACHED WITH THE CHINESE AUTHORITIES FOR THE INSTALLATION OF A RELIABLE COMMUNICATIONS LINK BETWEEN THE ROYAL OBSERVATORY AND THE DAYA BAY CONTROL CENTRE.

SINCE THE FOOD PATHWAY IS LIKELY TO BE THE PRINCIPAL CONCERN FOLLOWING ANY SERIOUS RELEASE OF RADIOACTIVITY FROM THE DAYA BAY PLANT, THE REPORT DEVOTES A REASONABLE AMOUNT OF COVERAGE TO THE MONITORING REQUIREMENTS FOR THE FOOD CHAIN.

THE NEED TO INITIALLY CONCENTRATE ON PRODUCE IN SHOPS AND MARKETS, SUCH AS FRUIT AND VEGETABLES, THAT MAY HAVE BEEN EXPOSED ΤΟ THE PLUME IS HIGHLIGHTED.

UNLIKELY

THAT

EVEN WITH VERY SERIOUS ACCIDENTS, IT IS UNACCEPTABLE CONTAMINATION OF THE WATER SUPPLY SYSTEM WOULD EVENTUATE.

THIS IS BECAUSE ANY DEPOSITION ON THE RESERVOIRS WOULD BE SUBJECT TO MASSIVE DILUTION BY THE VOLUME OF WATER IN THE RESERVOIR.

FURTHERMORE THE LEVEL OF RADIOACTIVITY IN THE WATER WOULD BE GREATLY REDUCED BY THE STANDARD WATER TREATMENT PROCESS.

THE REPORT GOES ON TO SAY THAT IT IS HIGHLY UNLIKELY THAT LIVESTOCK WOULD BE SIGNIFICANTLY CONTAMINATED UNLESS THEY HAD BEEN

GRAZING ON CONTAMINATED PASTURE.

CO-OPERATION FROM THE CHINESE AUTHORITIES WOULD ENSURE THAT ANY SUCH ANIMALS WOULD BE IDENTIFIED AND CHECKED FOR CONTAMINATION AT THE AFFECTED FARM. FOR MONITORING PURPOSES THE REPORT SUGGESTS THAT A SYSTEM OF REPRESENTATIVE SAMPLING WOULD BE JUSTIFIABLE.

OTHER HIGHLIGHTS OF THE REPORT INCLUDE:

*

THE SETTING UP OF A RADIATION PROTECTION ADVISORY PROVIDE INDEPENDENT ADVICE ON THE RISKS ASSOCIATED WITH A

POSSIBLE ACCIDENT AT DAYA BAY;

GROUP ΤΟ

*

THE NEED FOR EMERGENCY MONITORING MEASURING THE DOSE RATES FROM THE RADIOACTIVE PLUME AND FROM RADIOACTIVITY DEPOSITED ON THE GROUND;

TEAMS

CAPABLE

OF

*

THE NEED TO ENSURE THAT IN AN EMERGENCY THE INDIVIDUAL TO EMERGENCY WORKERS WAS MINIMISED, POSSIBLY THROUGH AN ISSUE OF DISPOSABLE PROTECTIVE CLOTHING;

RISK

*

THE NEED TO CONSIDER HOLDING SMALL STOCKS OF POTASSIUM IODATE TABLETS TO GIVE TO ANYONE WHO HAD BEEN CLOSE DAYA BAY SITE AT THE TIME OF A MAJOR ACCIDENT AND SUBSEQUENTLY RETURNED TO HONG KONG WITHIN 12 HOURS.
