Nuclear Storage in India
No modification or re-allocation can be done in labs, where radioactive materials are used
...


For any country the nuclear storage is a challenging issue
...


Personnel protection:
Radiation Safety Committee is the authorized team to take care of storage and steps to
avert any hazards
...
They monitor that exposure is safe below regulatory limits for all those
who are all involved in nuclear storage areas
...


Radiation Protection Rules (RPR) 2004 is adhered to strictly at all places and time
...
These authorized personnel will
maintain records containing the procedures and safety rules pertaining to radioactive materials
stored
...
A
competent authority has to approve his qualifications
...


Safety drill
If any radiation leak is detected or suspected, then it will be recorded for necessary
action
...
Safety drill is conducted to all personnel to see that they manage any
emergency
...
All details of doses of

1

the workers are recorded along with the radioactive materials stored
...
Any incidents
like diarrhea, vomiting, suffocation, dizziness and reddish skin are immediately recorded and
communicated to higher-ups for action
...


Safeguard practices
Maximization of distance from the radioactive source, shielding of Alpha radiation by air,
water, paper or any material are followed strictly
...
But it is difficult to escape from X-rays and Gamma rays
...


Thermo Luminescent Dosimeters, Film badges and direct reading Dosimeters are used to
judge the external dose measurement on individuals
...
For men and women, the limit of occupational exposure is same
...


The Board of Radiation and Isotope Technology located in Mumbai is the authorized unit
to import radioactive materials and a senior nuclear scientist possessing much experience will
receive it in his name
...
The Radiation
Safety Cell will be contacted by the user for disposal of radioactive materials
...
All details will
be communicated to AERB and BRIT
...
Radiation Safety Cell will give approval in writing for any changes in storage
...
RSO will be apprised of all works carried out by them
...

Symbols for safety
Radiation symbol is fixed on the rooms accommodating the Gamma cells and also on
Gamma cell
...


Safety suits
Radiation levels in various locations are entered in register
...


Radiation survey is done periodically by the authorized users and audited by Radiation
Safety Cell
...

The workers are advised to change their hand gloves frequently and dispose them as radioactive
waste item with a plastic bag
...


Safety Instructions
Centralized Radioactive source storage facility is available to store the disposed
radioactive materials
...


Only assigned Dosimeter to be worn
...


Not to tamper Dosimeter

The Radiation Protection survey is done during and after radioactive material handling to
ensure that contamination is eliminated and necessary follow up is done
...


All individuals routinely check their clothing during tea break, lunch break and after their
day duty
...


Chemical fume hoods and special iodination cabinets are used for protection
...

Each sign has the magenta, purple or black three bladed caution symbols on a yellow back
ground with a suitable message like ‘Caution Radiation area’, ‘Caution Radioactive material’ etc
...
The type and quantities with date are also seen in all labels
...

If any equipment is age old or poor in quality, we experience air borne radio activity
issues
...


Safe transportation
Radiation Safety Cell checks while transportation to see that required quantity permitted
by AERB is alone transported for storage
...


The radiation level on the surface of the package is measured by RSO
...
The logbook maintained by RSO will have details of
storage, location, date, time of supply, name of the individual carrying the package etc for future
reference and action
...


Any error committed in disposal of radioactive waste will lead to severe health problems
to outsiders
...


Before procurement of radioactive material, they plan with vision for correct method for
disposal as per rules designed by Radiation Safety Cell
...
Liquid wastes are kept in secondary containment
...
Employees are cautioned not to place any
radioactive material near the regular dust bins
...


Without prior permission, different isotopes are not dumped in the same container
...
Within a specified time it is disposed off
...

Guard at the gate
The frequent complaints received here is the danger due to spillage of radioactive
material or solution
...
Outside agencies are called
for major contamination taking place in the premises
...
Immediate medical attention will be rendered to
them after thorough medical checkup
...
No outsider will be allowed by the guard at the gate,
when any untoward incident has happened inside that area
...
The
room in which the contamination has happened is isolated or locked
...
Without their permission no material should be
thrown to dustbin or no one should leave without medical checkup
...

It’s true that nuclear storage needs up gradation
