(3) The employer may cease to treat an employee as a classified person only at the end of a calendar year except where - 

(a) an appointed doctor or employment medical adviser so requires; or

(b) the employee is no longer employed by the same employer in a capacity which is likely to result in significant exposure to ionising radiation during the remainder of the relevant calendar year.

    (2) For the purposes of paragraph (1), the employer shall make suitable arrangements with one or more approved dosimetry service for - 

(a) the making of systematic assessments of such doses by the use of suitable individual measurement for appropriate periods or, where individual measurement is inappropriate, by means of other suitable measurements; and

(b) the making and maintenance of dose records relating to each classified person.

    (3) For the purposes of paragraph (2)(b), the arrangements that the employer makes with the approved dosimetry service shall include requirements for that service - 

(a) to keep the records made and maintained pursuant to the arrangements or a copy thereof until the person to whom the record relates has or would have attained the age of 75 years but in any event for at least 50 years from when they were made;

(b) to provide the employer at appropriate intervals with suitable summaries of the dose records maintained in accordance with sub-paragraph (a) above;

(c) when required by the employer, to provide him with such copies of the dose record relating to any of his employees as the employer may require;

(d) when required by the employer, to make a record of the information concerning the dose assessment relating to a classified person who ceases to be an employee of the employer, and to send that record to the Executive and a copy thereof to the employer forthwith, and a record so made is referred to in this regulation as a "termination record";

(e) within 3 months, or such longer period as the Executive may agree, of the end of each calendar year to send to the Executive summaries of all current dose records relating to that year;

(f) when required by the Executive, to provide it with copies of any dose records;

(g) where a dose is estimated pursuant to regulation 22, to make an entry in a dose record and retain the summary of the information used to estimate that dose;

(h) where the employer employs an outside worker, to provide, where appropriate, a current radiation passbook in respect of that outside worker; and

(i) where the employer employs an outside worker who works in Northern Ireland or another member State, maintain a continuing record of the assessment of the dose received by that outside worker when working in such place.

    (4) The employer shall provide the approved dosimetry service with such information concerning his employees as is necessary for the approved dosimetry service to comply with the arrangements made for the purposes of paragraph (2).

    (5) An employer shall - 

(a) ensure that each outside worker employed by him is provided with a current individual radiation passbook which shall not be transferable to any other worker and in which shall be entered the particulars set out in Schedule 6; and

(b) make suitable arrangements to ensure that the particulars entered in the radiation passbook are kept up-to-date during the continuance of the employment of the outside worker by that employer.

    (6) The employer shall - 

(a) at the request of a classified person employed by him (or of a person formerly employed by him as a classified person) and on reasonable notice being given, obtain (where necessary) from the approved dosimetry service and make available to that person - 


(i) a copy of the dose summary provided for the purpose of paragraph (3)(b) relating to that person and made within a period of 2 years preceding the request; and

(ii) a copy of the dose record of that person; and



(b) when a classified person ceases to be employed by the employer, take all reasonable steps to provide to that person a copy of his termination record.

and in either case the employer shall take reasonable steps to inform the classified person of that entry and arrange for the approved dosimetry service to identify the entry in the dose record as an estimated dose or a notional dose as the case may be.

    (2) The employer shall, at the request of the classified person (or a person formerly employed by that employer as a classified person) to whom the investigation made under paragraph (1) relates and on reasonable notice being given, make available to that person a copy of the summary sent to the approved dosimetry service under sub-paragraph (a) of paragraph (1).

    (3) Subject to paragraphs (5) and (8), where an employer has reasonable cause to believe that the dose received by a classified person is much greater or much less than that shown in the relevant entry of the dose record, he shall make an adequate investigation of the circumstances of the exposure of that person to ionising radiation and, if that investigation confirms his belief, the employer shall, where there is adequate information to estimate the dose received by the employee - 

(a) send to the approved dosimetry service an adequate summary of the information used to estimate that dose;

(b) arrange for the approved dosimetry service to enter that estimated dose in the dose record of that person and for the approved dosimetry service to identify the estimated dose in the dose record as a special entry; and

(c) notify the classified person accordingly.

    (4) The employer shall make a report of any investigation carried out under paragraph (3) and shall preserve a copy of that report for a period of 2 years from the date it was made.

    (5) Paragraph (3) shall not apply - 

(a) in respect of a classified person subject only to an annual dose limit, more than 12 months after the original entry was made in the record; and

(b) in any other case, more than 5 years after the original entry was made in the record.

    (6) Where a classified person is aggrieved by a decision to replace a recorded dose by an estimated dose pursuant to paragraph (3) he may, by an application in writing to the Executive made within 3 months of the date on which he was notified of the decision, apply for that decision to be reviewed.

    (7) Where the Executive concludes (whether as a result of a review carried out pursuant to paragraph (6) or otherwise) that - 

(a) there is reasonable cause to believe the investigation carried out pursuant to paragraph (3) was inadequate; or

(b) a reasonable estimated dose has not been established,

the employer shall, if so directed by the Executive, re-instate the original entry in the dose record.

    (8) The employer shall not, without the consent of the Executive, require the approved dosimetry service to enter an estimated dose in the dose record in any case where - 

(a) the cumulative recorded effective dose is 20mSv or more in one calendar year; or

(b) the cumulative recorded equivalent dose for the calendar year exceeds a relevant dose limit.

    (2) In such a case, the employer shall - 

(a) take all reasonably practicable steps to inform each person for whom a dose assessment has been made of the result of that assessment; and

(b) keep a record of the assessment or a copy thereof until the person to whom the record relates has or would have attained the age of 75 years but in any event for at least 50 years from the date of the relevant accident.

    (2) The employer shall ensure that each of his employees to whom this regulation relates is under adequate medical surveillance by an appointed doctor or employment medical adviser for the purpose of determining the fitness of each employee for the work with ionising radiation which he is to carry out.

    (3) The employer shall ensure that a health record, containing the particulars referred to in Schedule 7, in respect of each of his employees to whom this regulation relates is made and maintained and that that record or a copy thereof is kept until the person to whom the record relates has or would have attained the age of 75 years but in any event for at least 50 years from the date of the last entry made in it.

    (4) Subject to paragraph (5), the employer shall ensure that there is a valid entry in the health record of each of his employees to whom this regulation relates (other than employees who have received an overexposure and who are not classified persons) made by an appointed doctor or employment medical adviser and an entry in the health record shall be valid - 

(a) for 12 months from the date it was made or treated as made by virtue of paragraph (5);

(b) for such shorter period as is specified in the entry by the appointed doctor or employment medical adviser; or

(c) until cancelled by an appointed doctor or employment medical adviser by a further entry in the record.

    (2) A radiation employer who makes any investigation pursuant to paragraph (1) shall make a report of that investigation and shall - 

(a) in respect of an immediate investigation, keep that report or a copy thereof for at least 2 years from the date on which it was made; and

(b) in respect of an investigation made pursuant to sub-paragraph (c) of paragraph (1), keep that report or a copy thereof until the person to whom the record relates has or would have attained the age of 75 years but in any event for at least 50 years from the date on which it was made.
