Real-Time Dosimetry Solution

In work environments with a higher radiation exposure risk or for personnel needing additional awareness of any exposure, like pregnant women, a real-time dosimeter may be judicious and sometimes even required by national legislation. Such electronic dosimeters are commonly called APD (active personal dosimeter). Dosilab proposes a family of APD systems, not just an APD. In contrast to a single APD, a system automatically stores the dose measurements during a work shift and tracks the total exposure over time.  

The APD performance requirements are similar in large or smaller organizations.  On the other hand, depending on the user’s environment a stand-alone or a networked system may be preferable. This is why we propose both solutions:

  • dosiNET: network solution with remote attribution stations and centralized database. The solution is scalable from a few up to dozens of attribution stations and can grow with your needs. Each attribution station can host from a few up to 16 APDS.
  • dosiLight: stand-alone solution directly connected to a local  PC  and single point of attribution and can host up to 2×4 APDs.

The dosiNET and dosiLIGHT active dosimetry systems are turn-key solutions designed to respond to the needs and requirements of the medical community potentially exposed to ionizing radiation sources:

  • High-end personal dosimeter, fully configurable and automatically adapted to measure the exposures of each workplace. It conforms to the latest international IEC-61526 norm and accurately measures dose from energies as low as 20keV.
  • Attribution units: wall mounted stand-alone stations or desk-top units connected to a PC to store and recharge the APD batteries.  
  • Software platform to
    – analyze and manage organization and personnel,
    – perform dose analysis, generate history and dose reports to authorities,
    – monitor dose budgets
  • Cost effective solution since the APDs are shared among users.  
  • Support and maintenance including periodic APD recalibration.

APD – Active Personal Dosimeter

The electronic dosimeter measures dose and dose rates. These measurements are displayed in real-time so the user has an immediate feed-back of his current exposure.  

The APD has been designed to respond to the medical professional key requirements:  a simple to use, precise and reliable instrument. This is why we made it manipulation-free and without any buttons. All personalization is automatically done during attribution, meaning when the user identifies himself to get a preconfigured dosimeter. This personalization includes alarm levels and dose measurement recording critera.

When a user returns a dosimeter to an attribution station, the measured dose is automatically transmitted to the database and the APD is available for someone else to use. Thus, the APDs are sharable among all registered users. This minimizes the number of needed APDs since not all staff members use a dosimeter at the same time.

The main characteristics of the APD are:

  • Name and first name display for easy identification of the current user
    – The user name and personalization information is downloaded during the APD assignment phase
    – Assignment phase takes a few seconds with the personal ID-Code code
  • Dose and dose rate measurements are indicated in :
    – Hp(10) and drHp(10) as personal deep dose and dose rate
    – HP(0.07) and drHp(0.07) as personal shallow dose and dose rate
    – Measuring range is from 1µSv to 100Sv and 1µSv/h to 10Sv/h respectively
  • Alarm levels are predefined for each user or task and automatically set at attribution:
    – Dose Alarm :           set to trigger at any user-defined dose level.
    – Dose Rate Alarm:     set to trigger at any user-defined dose rate level.
    All the alarms are both acoustic (beeps) and visual with flashing LEDs.  Alarms are also registered and saved in the database during the APD de-attribution phase. Furthermore, the radiation officer is notified when someone got exposed over the expected limit and thus can take the appropriate actions.
  • Maintenance-free: the APD has a rechargeable battery so no user maintenance is required. The attribution station automatically recharges the stored APDs.
  • Ergonomic: light instrument (less than 65gm) with different attachment solutions (pocket clip, pinch clip)

The dosiNET System architecture

The APD has been designed to easily integrate in the client’s LAN and server environment. All communication between the server and the stations or PC-host is based on the standard TCP/IP.

The system architecture is based on a classical Client-Server configuration where the server controls the access to the dosimetry database and various clients are:

  • dosiCLIENT is the program used by the radioprotection officer in order to manage the APD users, view and analyze the measured doses (France: upload the dose records to SISERI).
  • dosiSTATION is the attribution station where the APS are stored and recharged when not in use.
  • dosiLINK is the program installed on PCs to communicate between the table-top dosimeter management units and the server.

The dosiNET attribution stations and units

APDs are configured before use at any station or table-top units according to the parameterization defined by the radioprotection officer.

The APD-Station is an intelligent terminal where a user performs following operations:

  • Register a dosimeter for his own immediate use (attribution)
  • Return the APD after use, save the dose measurements (deattribution)
  • View his own dose measurement database

The APD-Station can hold up to 16 APDs.

The APD-Station charges the APD battery and communicates to the server via a standard RJ-45 connection. The APD-Station operates also in an autonomous way, thus in the event of a LAN interruption it remains fully functional since it has a  local, automatically synchronized, database.

APD Table-top unit
When only a few APDs are needed and a PC is available, the table-top units are a cost effective alternative to the stand-alone APD-stations. A table-top attribution unit connects to a PC via USB.

On the PC, the dosiLINK application lets the user attribute dosimeters in an identical way as on the APD-station.

The dosiNET Software

The dosiNET software package includes 3 applications:

  • dosiCLIENT: used to administer the users’ data and inspect/analyze the dose exposure measurements.    
  • dosiSERVER : controls the system peripherals via the standard TCP/IP LAN and thus set-up and monitors the APD use
  • MySQL database: this is the standard SQL database

The dosiCLIENT comes with an intuitive graphical user interface, manages the dosimetry data and APD usage. A login-access ensures that confidential data can be accessed only by authorized users.
The client module lets the system manager, radioprotection expert or other authorized personnel configure the radiation monitored environment, manage the wearer and analyze their radiation exposures. The main characteristics of the software environment are:

  • User registration and organization mapping
  • Chart and table analysis of radiation exposures: by dose / dose rates
  • Alarm monitoring
  • APD use monitoring
  • Dose records data export. Multiple national data formats supported. Excel export.

The dosiLIGHT system

dosiLIGHT offers a stand-alone, cost effective alternative to a dosiNET and suited for smaller organizations. In such environment only a single dosimeter access point is required.  In dosiLIGHT communication to the attribution units, the management of the user’s data and their dose exposure measurements are integrated in a single software package running on a standard PC.

All the functionality available in the dosiNET system is also available in dosiLIGHT. The limitation is that up-to 2 table-top attribution units with up to 4 dosimeters each can be connected to the host PC.

dosiLIGHT comes with a software installer which guides though the installation and configuration. This eliminates the needs for an on-site installation intervention and the associated costs. So, if you only need a few APDs to track dose exposure in real-time, dosiLIGHT is a cost effective alternative without any compromise on functionality or performance.
