For the purposes of this Section, the following term is defined:
"Fireproof containers" shall include steel or concrete containers and shall not include lead or other low-melting metals or alloys, unless the lead or low-melting metal or alloys are completely encased in steel.
In M1 Districts, unsealed radioactive materials shall not be manufactured, utilized, or stored (unless such materials are stored in a #fireproof container# at or below ground level) in excess of one million times the quantities set forth in Column 1 of the table in Section 38-2 of the Industrial Code Rule No. 38, relating to Radiation Protection adopted by the Board of Standards and Appeals of the New York State Department of Labor on October 10, 1955, effective December 15, 1955.
In M2 Districts, such materials shall not be manufactured, utilized, or stored (unless such materials are stored in a #fireproof container# at or below ground level) in excess of 10 million times the quantities set forth in Column 1 of the table cited in this Section. In M3 Districts no limits as to such permitted quantities shall apply.
In M1 or M2 Districts, no one of the following fissionable materials shall be assembled at any one point, place, or work area on a #zoning lot# in a quantity equal to or in excess of the amount set forth herein:
In addition, any establishment which provides radiation waste disposal services in the nature of collection or storage of radioactive waste from other #manufacturing uses# shall be prohibited in M1 or M2 Districts.
The Department of Health shall have exclusive jurisdiction to enforce and administer these hazards in accordance with the rules and regulations promulgated by the Board of Health. An appeal may be made to the Board of Health to permit the manufacture, utilization, or storage of unsealed radioactive materials or fissionable materials, in excess of the quantities set forth in Section 42-262 (Maximum permitted quantities of unsealed radioactive material) or Section 42-263 (Maximum permitted quantities of fissionable materials). In any case where the Board of Health determines that the radiation hazard on or beyond any #lot line# is remote and minimal, even in the event of an accident, the Board may permit such additional quantity.
