days, after receipt of the application and shall within 10 days after the examination
supply to the applicant 2 copies of a certificate certifying the date upon which the
examination took place and whether the applicant was found to be fit or unfit, as the
case may be, for employment in radiation work.

(3) For the purpose of this regulation the expression 'first employment'
includes re-employment in any work or process involving the handling of any
radioactive substance following a cessation of such employment for any period

examination, at intervals of not more than 14 months during the continuance of such
employment and is after each examination certified by the Board to be fit for such
employment.

(2) Notwithstanding anything contained in subregulation (1), the Authority may
require, by notice in writing served upon the proprietor of such undertaking, that
any person employed by him in any work or process involving the handling or
transport of any unsealed radioactive substance shall undergo medical examination
by the panel, including blood examination, at such time or at such lesser intervals
than those specified in subregulation (1) as the Authority, having regard to the
circumstances of the case, may consider expedient to safeguard the health of such
person; and if such person fails to submit to examination or, after examination, is
certified by the Board to be unfit for such employment, such proprietor shall,
forthwith upon receipt of notice in writing to that effect from the Authority, cease to
employ such person on such work or process.

undertaking or affected industrial undertaking in pursuance of the powers conferred
by subregulation (2), a copy thereof shall also be served upon the person to which
the notice relates.

exposure to radiation shall be deemed to indicate over-exposure thereto.





16. Radiation Board to keep records

of medical examinations

(1) The Board shall keep a record of every medical examination carried out by
the panel in accordance with these regulations and shall supply free of charge to any
person so examined, and to the proprietor of the affected undertaking or affected
industrial undertaking, as the case may be, in which such person is employed, a
certificate certifying the date upon which the examination took place and whether
such person was found to be fit or unfit to be employed in any work or process
involving the handling or transport of any unsealed radioactive substance. (L.N. 98
of 1970)

(2) Upon application, and upon payment of a fee of $65, the Board shall issue a
certified copy of any certificate referred to in subregulation (1) to the person to
whom such certificate relates and to any present or past employer of such person.
(L.N. 211 of 1989)

17. Medical examination and inquiry in cases

of suspected over-exposure to radiation

(1) If the Authority, as a result of information received or otherwise, has reason
to believe that any person employed in any affected undertaking or affected
industrial undertaking is suflering from over-exposure to radiation the Authority
shall, in the manner prescribed in regulation 14(2), require that such person be
medically examined by the panel; and if after such examination the Board is satisfied
that such person is suffering from the effects of over-exposure to radiation to an
extent requiring medical treatment, the Board shall, in addition to any action which
the Board may consider appropriate under regulation 14, issue free of charge to such
person a certificate certifying as to his condition.

(2) Without prejudice to anything contained in subregulation (1), if the
Authority has reason to believe that any person employed in any affected
undertaking or affected industrial undertaking is suffering from the effects of, or
appears to have been subject to, over-exposure to radiation, the Authority may
appoint one or more representatives to investigate the working conditions or the
working habits of such person, together with any equipment used by him and to
make report thereon to the Authority.

(3) A copy of any report made pursuant to the provisions of subregulation (2)
shall be forwarded by the Authority to the Board.

(4) If any person wilfully obstructs or, by knowingly giving false information,
endeavours to mislead any representation of the Authority appointed under
