APPENDIX 16-A TABLE 1 EXEMPTIONS Table 1-A. Radioactive Materials Item (a) Exempt concentrations. (1) Except as provided in paragraph (2) of this item, any person is exempt from the requirements of this Part to the extent that such person transfers, receives, possesses or uses products or materials containing radioactive material in concentrations not in excess of those listed in Table 2 of this Appendix. (2) No person may introduce radioactive material into a product or material knowing or having reason to believe that it will be transferred to persons exempt under paragraph (1) of this item or equivalent regulations of the United States Nuclear Regulatory Commission or any agreement State, except in accordance with specific license issued by the department or a similar license issued by the State Department of Labor, the New York City Department of Health, the United States Nuclear Regulatory Commission, any agreement State or the general license provided in item (h) of Table 6 of this Appendix.

Glossary Glossary
Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts. -

Element Symbol: Pb Atomic Number: 82
LEAD Element Symbol: Pb Atomic Number: 82 An initiative of IYC 2011 brought to you by the RACI KERRY LAMB www.raci.org.au LEAD Element symbol: Pb Atomic number: 82 Lead has atomic symbol Pb and atomic number 82. It is located towards the bottom of the periodic table, and is the heaviest element of the carbon (C) family. The chemical symbol for lead is an abbreviation from the Latin word plumbum, the same root word as plumbing, plumber and plumb-bob still commonly used today. Two different interpretations are associated with the word plumbum, namely “soft metals” and “waterworks”. No-one knows who discovered lead, the metal having been known since ancient times. Archaeological pieces from Egypt and Turkey have been found dating to around 5000 BC. Lead is also mentioned in the book of Exodus in the Bible. The Hanging Gardens of Babylon were floored with soldered sheets of lead, while there is evidence to suggest the Chinese were manufacturing lead around 3000 BC. Some reports suggest that lead was probably one of the first metals to be produced by man, and this is likely so given its worldwide occurrence and its relative ease of extraction. In alchemy, lead was considered the oldest metal and was associated with the planet Saturn. Lead makes up ~0.0013% of the earth’s crust. It is rare that metallic lead occurs naturally. Lead is typically associated with zinc, copper and silver bearing ores and is processed and extracted along with these metals. When freshly cut pure lead is a bluish-white shiny metal that readily oxidises in air to the grey metal that is more typically known. -
