LCQ18: Radiological contamination
Following is a question by the Hon Andrew Leung and a written reply by the
Secretary for Food and Health, Dr York Chow, in the Legislative Council today
(February 15):
Question:
It has been reported earlier that a country found that the level of radioactive
contamination of automotives made in Japan exceeded the normal standard and thus
banned the import of such automotives. Regarding the radioactive contamination
of Japanese products, will the Government inform this Council:
(a) apart from food products, whether the authorities have conducted regular
sample tests since March last year on the level of radioactive contamination of
products (including auto parts and components, electronic components, drugs,
toys, cosmetic products, clothing, stationery items, daily necessities and
medical equipment, etc.) made in Japan; if they have, of the number of sample
tests conducted and the test results; if not, the reasons for that;
(b) given that Japan announced in December last year the leakage of contaminated
water with a high concentration of radioactive substances (the contaminated
water), of the government departments in Hong Kong which are responsible for
assisting those Hong Kong people who are worried about having come into contact
with the contaminated water in Japan to conduct checks; and
(c) given that a health desk was set up by the authorities at the Hong Kong
International Airport for passengers arriving at Hong Kong from Japan for
voluntary checking of their level of radioactive contamination, of the number of
members of the public who were checked at the health desk, and whether the level
of radioactive contamination of any of them exceeded the normal standard;
whether the authorities have compiled statistics on the members of the public
who went to public or private hospitals, clinics or laboratories on the own for
treatment or checking upon suspension of the health desk service since May last
year; if they have, of the statistics; if not, the reasons for that?

President,
Radiological contamination in products can be surface contamination or
contamination of raw materials. Surface contamination may be removed through
suitable decontamination measures. Hence, unless a particular product comes from
the vicinity of the source of a nuclear accident and is not properly
decontaminated, the risk of persons being cross-contaminated from such a product
is extremely remote. Contamination of raw materials may be avoided through
testing and certification processes in industrial manufacturing. Both types of
contamination can be detected using radiological monitoring equipment.
According to a joint news release of the International Civil Aviation
Organization, the International Atomic Energy Agency, the International Maritime
Organization, the World Health Organization, the World Meteorological
Organization, the World Tourism Organization and the International Labour
Organization dated April 14, 2011, screening of radiation for health and safety
purposes is currently considered unnecessary at airports and seaports around the
world.
As regards the ban of automotives made in Japan by a certain country alleged in
the preamble of the question, according to our research, there was a media
article on November 24, 2011 which said that Mongolia would impose a ban on the
import of cars from Japan which have not undergone radiological inspections. The
same article quoted the Japanese Ministry of Foreign Affairs as to be checking
on the situation with the Mongolian authorities.
My reply to the three parts of the question, with consolidated information from
relevant policy bureaux and departments, are as follows:
(a) Since the Fukushima nuclear accident in March 2011, the Customs and Excise
Department (C&ED) has stepped up its efforts at the airport and seaports to
monitor goods imported from Japan (including pharmaceutical products, cosmetics,
personal care products, family products, other consumer products, etc.) for
safety testing of radiation levels, in order to prevent radiologically
contaminated goods from entering Hong Kong.
As at early February this year, C&ED has checked over 613,000 air consignments
and over 15,000 sea consignments from Japan. No samples were found to have been
radiologically contaminated.
(b) According to the radiation monitoring readings released by the Japanese
Ministry of Education, Culture, Sports, Science and Technology (MEXT), the
environmental radiation levels throughout Japan (except Fukushima Prefecture)
have come down to levels comparable to that before the nuclear accident, and
these levels are far below what would trigger tissue reactions. As regards
Fukushima Prefecture, the 20-kilometre radius around the Fukushima Daiichi
Nuclear Power Plant and other areas with higher levels of radiation remain
designated as an evacuation zone by the Japanese Government, where public access
is restricted. In this connection, travellers visiting Japan need not worry
about being exposed to radiation or radiological contamination at harmful
levels.
As for radiological contamination in seawater, MEXT released radioactivity
concentration readings at the offshore of Miyagi, Fukushima and Ibaraki
Prefectures, located more than 30 kilometres away from the Fukushima Daiichi
Nuclear Power Plant. According to the data, there were minute amounts of
radioactive caesium found in some of the samples, but its activity is far below
the guideline levels for determination of the closure of bathing areas. On the
other hand, Fukushima Prefecture is located 3,000 kilometres away from Hong
Kong, and the prevailing sea current near the prefecture predominantly drifts
towards the northeast, hence the chances of Hong Kong waters being contaminated
in this connection is minimal. Despite so, following the nuclear accident, the
Hong Kong Observatory has stepped up its seawater radiation monitoring and
collected seawater samples from Hong Kong waters with the assistance of the
Environmental Protection Department. The measurement results show that no
artificial radionuclide is detected in any seawater samples collected within
Hong Kong waters.
Given that the radiological impact on health is most significant at the source
of the nuclear accident, accident and emergency (A&E) departments of public
hospitals in Hong Kong would determine whether further examination is necessary
for a patient on the basis of his travel history to Fukushima Prefecture and his
clinical presentation.
(c) In order to assist travellers returning from Japan who were worried about
their personal health, the Government set up a health desk at the Hong Kong
International Airport from March 16 to May 12, 2011 which provided voluntary
radiation checks for travellers in need. During the period, a total of 3,936
travellers received assistance. No cases of radiological contamination were
found.
Since the Fukushima nuclear accident, A&E Departments of local public hospitals
have not found any cases of radiological contamination, nor received any cases
which meet the A&E triage guidelines devised in response to the Fukushima
nuclear accident as mentioned above. We have not been informed of any cases from
the private healthcare sector.
