[ RadSafe ] Restrictions on usage of radiation symbols in India

Fri Jun 29 12:25:34 CDT 2007

For what it's worth on casual misuse of the radiation warning symbols/signs 
in an odd corporate situation. Several decades ago,  while I was living and 
working in Massachusetts [so this is not an urban legend], a tractor trailer 
load of then very expensive computer components fromm a Massachusetts 
manufacturer was hijacked by thieves. Inside the truck, the contents were 
falsely labelled with radiation warning labels by the manufacturing company.

The thieves abandoned the truck believing the goods were contaminated and 
the tractor trailer was found abandoned near the Mass Pike. Fear of 
radiation comes through again to force people to do things that make no 
sense.

Dear John,

In India,Rule 14 of Atomic Energy (Radiation Protection) Rules 2004 is 
titled "Radiation  symbol  or warning signs" and specifies where the symbols 
can be used

Rule 14  Radiation symbol or Warning sign:-

(1) The radiation symbol or warning sign
shall be conspicuously and prominently displayed at all times -
(a) on externally visible surfaces of radiation equipment, and containers 
for
storage of radioactive materials; packages for radioactive materials and
vehicles carrying such packages;
(b) at the entrance to the room housing the radiation generating equipment; 
and
(c) at the entrance of controlled area and supervised area.
(2) The radiation symbol shall not be used for any purpose other than those
mentioned in these rules.
(3) The specification of the radiation symbol or warning sign shall be as
prescribed by the competent authority, by order for that purpose.

the Atomic Energy Act 1962 and rules may be downloded from www.aerb.gov.in

Don,
You may be right about what is allowable.  I know that
a license is to use signs and label to identify
radioactive sources and areas.  Our thought that using
them inappropriately was "misleading" to our
surveyors. I sounds like you are doing what we do
regarding the use of labels.

Yes, it is trefoil, (a symbol in the design of a
trifoliate leaf).  Another example of why your spell
checker should be left on.  The NRC calls it a
three-bladed design
