대기 기준Radionuclides has been designated as a hazardous air pollutant under section 112 of the Clean Air Act. /Radionuclides/
DOT Emergency Guidelines/GUIDE 162: RADIOACTIVE MATERIALS (LOW TO MODERATE LEVEL RADIATION)/ Health: Radiation presents minimal risk to transport workers, emergency response personnel and the public during transportation accidents. Packaging durability increases as potential hazard of radioactive content increases. Undamaged packages are safe. Contents of damaged packages may cause higher external radiation exposure, or both external and internal radiation exposure if contents are released. Low radiation hazard when material is inside container. If material is released from package or bulk container, hazard will vary from low to moderate. Level of hazard will depend on the type and amount of radioactivity, the kind of material it is in, and/or the surfaces it is on. Some material may be released from packages during accidents of moderate severity but risks to people are not great. Released radioactive materials or contaminated objects usually will be visible if packaging fails. Some exclusive use shipments of bulk and packaged materials will not have "RADIOACTIVE" labels. Placards, markings and shipping papers provide identification. Some packages may have a "RADIOACTIVE" label and a second hazard label. The second hazard is usually greater than the radiation hazard

일반 설명

A white crystalline mass. Mildly toxic. Not combustible but accelerates burning of combustible materials. May explode in a fire if in large quantities or if the combustible material is finely divided. Toxic oxides of nitrogen are produced in fires. Mildly radioactive. Radioactive materials emit certain rays detectable only by instruments. Minimal radiation hazard in transport. No protective shielding for packages is required.

제조 및 합성 방법

제조 방법

The phosphates are dissolved in cone, hydrochloric acid and precipitated with oxalic acid, and the thoroughly washed precipitate is extracted with warm aqueous Na2CO3. Most of the rare earths stay in the residue, while the thorium dissolves in the form of a carbonate complex, Na6Th(CO3)5. The material is freed of the remaining traces of rare earths by repeated crystallization in the form of the sulfate Th(SO4)28H2O. The procedure consists of precipitation of the hydroxide with ammonia and solution of the latter in sulfuric acid to re-form the sulfate. The precipitate from the last purification stage is dissolved in nitric acid to yield the nitrate.

so follow this GUIDE as well as the response GUIDE for the second hazard class label. Some radioactive materials cannot be detected by commonly available instruments. Runoff from control of cargo fire may cause low-level pollution. /Thorium nitrate, solid/
/GUIDE 162: RADIOACTIVE MATERIALS (LOW TO MODERATE LEVEL RADIATION)/ Fire or Explosion: Some of these materials may burn, but most do not ignite readily. Uranium and Thorium metal cuttings may ignite spontaneously if exposed to air ... . Nitrates are oxidizers and may ignite other combustibles ... . /Thorium nitrate, solid/
/GUIDE 162: RADIOACTIVE MATERIALS (LOW TO MODERATE LEVEL RADIATION)/ Public Safety: CALL Emergency Response Telephone Number ... . Priorities for rescue, life-saving, first aid, fire control and other hazards are higher than the priority for measuring radiation levels. Radiation Authority must be notified of accident conditions. Radiation Authority is usually responsible for decisions about radiological consequences and closure of emergencies. As an immediate precautionary measure, isolate spill or leak area for at least 25 meters (75 feet) in all directions. Stay upwind. Keep unauthorized personnel away. Detain or isolate uninjured persons or equipment suspected to be contaminated
delay decontamination and cleanup until instructions are received from Radiation Authority. /Thorium nitrate, solid/
/GUIDE 162: RADIOACTIVE MATERIALS (LOW TO MODERATE LEVEL RADIATION)/ Protective Clothing: Positive pressure self-contained breathing apparatus (SCBA) and structural firefighters' protective clothing will provide adequate protection. /Thorium nitrate, solid/
