Ohio Admin. Code 3701:1-38-15 - Control of exposure from external sources in high and very high radiation areas
(A) Control of access to high radiation areas
shall be maintained by the licensee or registrant.
(1) Control of access shall be maintained by
ensuring that each entrance or access point to a high radiation area has one or
more of the following features:
(a) A control
device that, upon entry into the area, causes the level of radiation to be
reduced below that level at which an individual might receive a deep dose
equivalent of one millisievert (0.1 rem) in one hour at thirty centimeters from
the source of radiation or from any surface that the radiation penetrates;
or
(b) A control device that
energizes a conspicuous visible or audible alarm signal so that the individual
entering the high radiation area and the supervisor of the activity are made
aware of the entry; or
(c)
Entryways that are locked, except during periods when access to the areas is
required, with administrative and/or engineering control over each individual
entry.
(2) In place of
the controls required by paragraph (A)(1) of this rule, in the case of a high
radiation area, the licensee or registrant may substitute continuous direct or
electronic surveillance that is capable of preventing unauthorized
entry.
(3) The licensee or
registrant may apply to the department for approval of alternative methods for
controlling access to high radiation areas.
(4) The licensee or registrant shall
establish the controls required by paragraphs (A) (1) and (A)(3) of this rule
in a way that does not prevent individuals from leaving a high radiation
area.
(5) The licensee is not
required to control each entrance or access point to a room or other area that
is a high radiation area solely because of the presence of radioactive
materials prepared for transport and packaged and labeled in accordance with
the regulations of the United States department of transportation provided
that:
(a) The packages do not remain in the
area longer than three days; and
(b) The dose rate at one meter from the
external surface of any package does not exceed 0.1 millisievert (0.01 rem) per
hour.
(6) The licensee
is not required to control entrance or access to rooms or other areas in
hospitals solely because of the presence of patients containing radioactive
material, provided that there are personnel in attendance who are taking the
necessary precautions to prevent the exposure of individuals to radiation or
radioactive material in excess of the established limits in paragraph (A) of
rule
3701:1-38-13
of the Administrative Code and to operate within the ALARA provisions of the
licensee's radiation protection program.
(7) The registrant is not required to control
entrance or access to rooms or other areas containing sources of radiation
capable of producing a high radiation area as described in paragraphs (A)(1) to
(A)(4) of this rule if the registrant has met all the specific requirements for
access and control specified in other applicable rules, such as, the
requirements for industrial radiography, x-rays in the healing arts, and
particle accelerators as provided in Chapters 3701:1-66,
and
3701:1-67, and 3701:1-68 of the Administrative
Code.
(B) In the case of
access to a very high radiation area, the licensee or registrant shall control
access as follows:
(1) In addition to the
requirements in paragraph (A) of this rule, and except as provided in paragraph
(B)(2) of this rule, the licensee or registrant shall institute measures to
ensure that an individual is not able to gain unauthorized or inadvertent
access to a very high radiation area. This requirement does not apply to rooms
or areas in which diagnostic x-ray systems are the only source of
radiation.
(2) The registrant is
not required to control entrance or access to rooms or other areas containing
sources of radiation capable of producing a very high radiation area as
provided in paragraph (B)(1) of this rule if the registrant has met all the
specific requirements for access and control specified in other applicable
rules, such as, requirements for industrial radiography, x-rays in the healing
arts, and particle accelerators as provided in Chapters 3701:1-66,
and
3701:1-67, and 3701:1-68 of the Administrative
Code.
