Except for a person who applies tritium, promethium 147, or radium to, or a person who incorporates tritium, promethium 147, or radium into, the following products, a person shall be exempt from chapters 67 through 69 to the extent that the person receives, possesses, uses, transfers, owns, or acquires the following products:

(a) Twenty-five (25) millicuries of tritium per timepiece;

(b) Five (5) millicuries of tritium per hand;

(c) Fifteen (15) millicuries of tritium per dial (bezels when used shall be considered as part of the dial);

(d) One hundred (100) microcuries of promethium 147 per watch or two hundred (200) microcuries of promethium 147 per any other timepiece;

(e) Twenty (20) mirocuries of promethium 147 per watch hand or forty (40) microcuries of promethium 147 per other timepiece hand; and

(f) Sixty (60) microcuries of promethium 147 per watch dial or one hundred twenty (120) microcuries of promethium 147 per other timepiece dial (bezels when used shall be considered as part of the dial).

6811.4

The levels of radiation from hands and dials containing radium or promethium 147 shall not exceed, when measured through fifty (50) milligrams per square centimeter of absorber as follows:

(a) For wrist watches - one-tenth (0.1) millirad per hour at ten (10) centimeters from any surface;

(b) For pocket watches - one-tenth (0.1) millirad per hour at one (1) centimeter from any surface; and

(c) For any other timepiece - two-tenths (0.2) millirad per hour at ten (10) centimeters from any surface.

6811.5

Except for a person who applies tritium, promethium 147, or radium to, or a person who incorporates tritium, promethium 147, or radium into the following products, a person shall be exempt from chapters 67 through 69 to the extent that the person receives, possesses, uses, transfers, owns, or acquires the following products:

(a) Lock illuminators containing not more than fifteen (15) millicuries of tritium or not more than two (2) millicuries of promethium 147 installed in automobile locks. The levels of radiation from each lock illuminator containing promethium 147 shall not exceed one (1) millirad per hour at one (1) centimeter from any surface when measured through fifty (50) milligrams per square centimeter of absorber;

(b) Balances of precision containing not more than one (1) millicurie of tritium per balance, or not more that five-tenths (0.5) millicuries of tritium per balance part;

(c) Automobile shift quadrants containing not more than twenty-five (25) millicuries of tritium;

(d) Marine compasses containing not more that seven hundred fifty (750) millicuires of tritium gas and other marine navigational instruments containing not more than two hundred fifty (250) millicuries of tritium gas;

(e) Thermostat dials and pointers containing not more that twenty-five (25) millicuries of tritium per thermostat;

(f) Glow lamps containing not more than ten (10) microcuries of tritium per lamp; and

(g) Spark gap tubes containing not more than thirty (30) microcuries of promethium 147. The levels of radiation from each spark gap tube containing promethium 147 shall not exceed five-tenths (0.5) millirad per hour at one (1) centimeter from any surface when measured through seven (7) milligrams per square centimeter of absorber.

6811.6

Authority to transfer possession or control by the manufacturer, processor, or producer of any equipment, device, commodity, or other product containing source, byproduct, or special nuclear material intended for use by the general public shall not be granted under chapters 67 through 69 of this title.

6811.7

6811.8

The resins specified in § 6811.7 shall have been manufactured or imported in accordance with a specific license issued by the NRC, or shall have been manufactured in accordance with specifications contained in a specific license or equivalent licensing document issued by the Director or any agreement state to the manufacturer of the resins pursuant to licensing requirements equivalent to those in §§ 32.16 and 32.17 of 10 C.F.R.
