The Federal Office for Radiation Protection (BfS) intends to expose the general population to low-frequency magnetic fields

in Germany via a representative sample. The determination of the exposure of individual test subjects

is done by wearing a magnetic field recorder (exposimeter) for a period of 24 hours. Additional Information

are to be obtained by keeping a daily log and answering questions.

It is planned to outsource the following subtasks from this project:

a) Setting up and operating a database with web-based access and securing data access via cloud

b) Recruitment of 2000 test subjects

c) Technical preparation and follow-up of the exposimeters

d) Handover, instruction of the exposimeter and measurement data transmission

Establishment and operation of a database hosted in compliance with data protection regulations with web-based access

The database is intended to be used for every recruitment process and interview conducted

a) contain the answers to the initial interview of the persons contacted in the recruitment process, but then

do not participate in the sample or data collection (non-responders) and

(b) contain all of the following data from the persons participating in the subsequent sample or data collection.

In doing so, it is necessary to store the recorded data of the persons in a categorized manner and to send them to the

BfS:

(1) The data records shall be kept pseudonymously. The contact details (address, telephone number and e-mail address)

of the test persons should only be known to the future service provider and must be specially protected. The

Key that assigns the data must be organized by the service provider, stored separately and securely.

(2) The persons participating in the sample should use their self-generated data (daily log, answers from

the questionnaire) independently with an Internet-enabled device via a web-based online access to the

Transfer database. The tender shall be accompanied by a concept with regard to these two requirements.

Recruitment of 2000 test subjects

In order to take into account the geographical population density distribution and thus different living environments, the

BfS has made a pre-selection of municipalities from which test subjects are to be recruited. The pre-selection was made on

The basis of the database of the Federal Statistical Office, generated by means of a weighted random number generator and is attached to the tender documents.

Technical preparation and follow-up of the exposimeters

Configuration of the exposimeters. The Bfs provides the service provider with configured exposimeters

available for the execution of the order. At the beginning of the project, the BfS will provide a technical briefing on the

employees of the service provider involved in the handling of the exposimeters.

Preparation and follow-up of the exposimeters.The service provider must carry out technical preparation and follow-up work on the exposimeters for each survey process.

Perform:

Preparation:

- Verification of the configuration and the state of charge

- Checking the functionality/accuracy by means of a Helmholtz coil

- Calibration IMU (internal gyroscope)

- Clearing the internal memory:

Wrapping Up

- Inspection of the equipment for mechanical damage

- Charging the exposimeter via USB

- Readout of the measurement data

- Storage of measurement data (mmm files, csv files)

- Review of measurement data

- Upload of the measured values to the database

The data sets from the exposimeters are read out using the software of the manufacturer of the exposimeters.

Handover and briefing

The handover of the exposimeters as well as the access data for the web-based online access to the participating

Test subjects must be sent by post or in person within 2 weeks of successful recruitment.

A briefing of the activities to be carried out by the test persons and of the handling of the exposimeter has

within three working days by the service provider in person or by video conference. Among other things,

the measurement period, i.e. the period for wearing the exposimeters, is agreed upon, preferably evenly distributed on 7 days of the week

become. Finally, you have to make an appointment for the interview and the organization of the

reversal of the exposimeter.

The duration of this briefing is estimated at 20 minutes. Shipping or travel costs incurred for this subtask

are to be estimated accordingly and presented in the offer.

Cover letter, questionnaire, daily protocol

At the start of a survey process, the test persons should be able to use a web-based online access to be implemented

Access to three sub-areas: The first sub-area is to provide information on the project (Annex 2 of the LB) and the

Data protection including a declaration of consent under data protection law. Sub-area 2 is to consist of the questions on

person and the domestic condition (sub-areas A and B in Appendix 3 of the LB) as well as the test persons should be in the form of

of a daily protocol (Appendix 4 of the LB) while wearing the exposimeter their course of the day online, or in paper form

can document. Events such as rest periods, changes of location or special events are recorded in this protocol

to be noted. The questions in the third sub-area should only be answered after wearing the exposimeter or after the 24-hour measurement.

(sub-area C in Appendix 3 of the LB). They include, among other things, queries on possible sources of electromagnetic

Fields.

Reversal

After the measurement data has been collected (24-hour measurement), a personal interview of approx. 20 minutes is conducted with the test persons

Perform. It is used to check the comprehensibility of the daily protocol, the completeness of the questionnaire, the

Elimination of any ambiguities and the inclusion of any additional detailed information.

After receiving the exposimeter, the complete data set (.mmm files) must be read from the device and stored in the

Database together with the information from the questionnaires, the daily log, the postal code from which the respondent

as well as to file any additional information within 10 working days. One

summary notification of the completed survey processes has been sent to the BfS by e-mail on a daily basis

to be done.

Pilot phase

An upstream pilot phase with 5% of the total number of people, distributed as evenly as possible across all

Community size classes, is intended to optimize the recruitment process, the timing and the

Identification of risks for the successful implementation of the project.

Project management.

The tender must be accompanied by a complete project plan. Any minor adjustments made in the project planning or

implementation after the pilot phase must be coordinated with the BfS.

In the pilot phase, a weekly jour fixe is to be planned, followed by a monthly jour fixe. To the respective

Deadlines are provided by the service provider with a status report on the absolute and percentage progress of the project as well as a forecast

on the expected end of the project as well as on risks and open points. At the end of the overall project,

to prepare a barrier-free report on the results of the four subtasks, in particular with an assessment of the

achieved representativeness and socio-demographic distribution of the recruited test subjects.

Duration of the project.

The project must be completed no later than 24 months after the award of the contract.

Handing over the exposimeters.

The BfS will provide the service provider with exposimeters free of charge for the duration of the implementation of the project.

Number of exposimeters is 30 pieces.

Loss of exposimeters.

A damage and loss rate of the exposimeters must be estimated by the service provider and taken into account during the project and

Scheduling to consider.

According to "Guiding Principle 01/01 - Principle of self-coverage according to No. 11 of the VV to § 34 BHO", the exposimeters generally remain

uninsured.

Expense allowance for the test persons

The BfS does not provide for an expense allowance or remuneration for the test persons.
