cycle are received. Unused TLD cards should not be retained at the users end for use during subsequent period.
Please note all the TLD cards sent should be accounted for by the user institution. In exceptional cases when fresh
cards are not received in time, the old TLD cards may be continued to be used until the new cards arrive, but the
extended period of use should be clearly indicated on the TLD cards by sticking a label on the polythene pouch and
in the accompanying TLD/5 forms. Late return/ non-return of TLD cards do not serve the purpose of personnel
monitoring.
b. The institutions should always send back the TLD cards to be read by registered post / courier. Sending of TLD by
air courier should be avoided as it is possible that airport authorities will screen the package under X-Ray machine
at the airport.
c. If a TLD card is not used, the remark “not used” should be written on the TLD card as well as in the TLD/5 form
against the name the card was assigned for.
d. While returning, arrange the TLD cards in same order as listed in TLD/5 forms. Write the nature of radiation
sources handled against the respective names in the TLD/5 form.
e. Use plastic boxes for returning the cards to avoid loss during transit. The boxes in which we are sending the TLD
cards may be reused for returning the TLD cards.
f. If you envisage that some workers who are already availing the service are not going to work in radiation field in
the immediate future, the information about that should be sent at least one month before the start of the next
cycle. The no. of cards to be sent will be reduced accordingly.
g. If high exposures to persons are suspected, their TLD cards can be returned immediately to us along with details
of the incidence for urgent processing and necessary action.
h. If a TLD card is lost at your end, a declaration stating the circumstances under which the card was lost, duly
signed by the user and the officer-in-charge/R.S.O./Physicist, should be sent to us. The details of the radiation work
done and the dose expected during the monitoring period should also be intimated to us. (Note that an amount of
Rs.125/- will be charge for replacement).
8) CHANGES IN EQUIREMENT/ADDITION/DELETION OF NAMES
Specify the changes in the requirements, if any, clearly in the following format.
a. Names to be added.
b. Names to be deleted.
c. Total monthly requirement of TLD cards.
d. Additional requirement of chest/wrist TLD cassettes, if any, kindly do not state your requirements vaguely e.g.
some TLD cards, use above format for clarity.
e. A personal data form should be filled in for each radiation worker and the same should be sent to us. This will
help us to maintain correct life-time dose records of the radiation workers. All new names should be accompanied
by the completed personal data forms. A copy of personal data (TLD/4) form is attached along with this manual.
f. Intimation regarding changes in the requirements or suspension of service, if any, should reach AVANTTEC
LABORATORIES PVT LTD one month in advance of the intended period of use. This intimation should be sent by a
separate letter duly signed by authorized person, and not in the TLD/5 form.
g. All cassettes and TLD cards once dispatched by us, irrespective of whether used or unused will be charged.
