Personnel Radiation Monitoring Services
What is TLD and what is a TLD badge ?
TLD means Thermo luminescent Dosimeter. Thermo luminescence means thermally stimulated emission of light. Certain materials (CaSO4: Dy phosphor) absorb energy on exposure to Ionising radiations. On heating, the energy is released in the form of visible light. The quantity of visible light emitted is found to be proportional to the energy absorbed by the TL- Phosphor material. TLD badges are used to detect radiation at levels that can be harmful to humans. They emit light in amounts proportional to the radiation received. Thermoluminescent dosimeters (TLDs) are made from materials that measure cumulative exposure to ionizing radiation. They are worn for periods of approximately three months and are then processed to determine the dosage of radiation detected. TLD badges are logged to maintain cumulative records of an individual’s exposure to radiation over an extended period of time. TLD badges include several types of thermoluminescent dosimeters, devices that can measure doses as low as millirem.
What is meant by Personnel Monitoring Service?
Why Personnel monitoring is required?
- To obtain an assessment of the effective dose and where appropriate, the equivalent dose in significantly exposed tissues, so as to demonstrate compliance with managerial regulatory requirements.
- To contribute to the control of operation & design of facilities.
- In case of accidental overexposure, to provide valuable information for the support of appropriate health treatment.
How to start Personnel Radiation Monitoring Service (PMS)
There is two forms, ( PMS-1 ) and other is ( PDF-2 )
(PMS-1 ) form for registration of Centre & form for registration of radiation personnel under the Centre. To start Personnal Radiation Monitoring Service PMS, first download the ( PMS–1 ) & ( PDF–2 ) forms.
For ( PMS-1 ) form,fill all details of your Centre such as name, address, phone number, pin code, email address. Fill in details of radiation installation such as make, model, radio-isotope, activity, installation, and in the endkindly affix stamp of your centre & signature of Head of centre.
For form fill all detail of radiation personnel such as name of address of present organization where he/she is working, full nameof radiation personnel, Date of birth, Birthplace, qualification, nature of work of radiation personnel. Make sure that on the form, the radiation workers signature along with details and signature of Radiation Safety Officer& Head of the institution are done.
Kindly note that incomplete forms will be rejected.
Also attach photos and zerox copy of photo ID for each PDF-2 form.
Depending on the number of Radiation personnel to be monitored, attach a AT PAR cheque or Demand draft in favour of RENENTECH LABORATORIES PVT LTD payable at Mumbai.Payment table is attached for your reference.
Your payment amount includes charges for one control card which will be sent to you everytime along with your personnel TLD cards. Control measures the background radiation of your Centre.For more info on control card, kindly refer to FAQ 15
Dispatch all the forms duly completed with photos and Xerox copy of ID proof.
As soon as we receive the application forms, we will dispatch them to BARC for approvals which normally takes 10 working days.
As soon as BARCapproval for your Centre and radiation personnelis received, we will start theirPersonnel Radiation Monitoring Service by dispatching the TLD Badges by Courier or Postal Registered Post as applicable.
Make sure to please read the User Instruction Manual (accompanied by TLD badges) and inform & train your radiation personnel regarding the step and proceduresfor using the TLD badges. (A copy of User instruction Manual can be downloaded along with the TLD application forms)
Can I start Personnel Radiation Monitoring Service ( PMS ) in any month?
When will we get new service period cards after starting PMS?
We have a Digital X-ray Machine. We were told by the salesman that we would not need radiation badges anymore. Is this true?
While Digital X-ray Machines are safer than traditional x-ray machines, in terms of continues retake, as single radiograph is sufficient, even if image is not proper it can be manipulated using digital technology. Digital x-rays use radiation to cast an image on the digital detector. Although the typical digital imaging unit can create an image using less radiation, but the radiation is not so less that the person need not be monitored. Some studies have shown an increase in exposure to patients and staff for a variety of reasons.
Although the energy required to produced digital radiography is less, but due to the previous tendency of traditional x-ray, high exposure are given which cause high dose to patient and staff which need to be monitored, also digital x-ray never reduced the chance of accidents.
