Please note: Symbols for LD50 values
Some devices may read symbols incorrectly in Word and possibly HTML and PDF. The Greek letter ‘mu’ is used in five provisions (LD50) in the Gene Technology Regulations 2001 as part of a recognised international symbol indicating ‘micrograms’. This symbol is usually displayed correctly. However, some devices may display it incorrectly, making units read as ‘mg’ (milligrams), which significantly changes the meaning of the legislation. ‘mg’ is not used in the Gene Technology Regulations 2001. The definitive legal PDF versions, where the problem will not occur on most devices, can be accessed from the ‘Download’ tab on ComLaw web pages linked from the OGTR website.
When accessing large documents (over 500 KB in size), it is recommended that the following procedure be used:
Attempting to open large documents within the browser window (by left-clicking)
may inhibit your ability to continue browsing while the document is
opening and/or lead to system problems.
To view PDF (Portable Document Format) documents, you will need to have a PDF reader installed on your computer. A number of PDF readers are available through the Australian Government Information Management Office (AGIMO) Web Guide website.
