This document discusses the use of thermoluminescent dosimeters for monitoring radiation exposure. It notes that thermoluminescent dosimeters are the modern technology used in most EU countries. They have tissue-equivalent materials that improve dose measurement accuracy. Thermoluminescent dosimeters are easy to use as self-contained units and have a very low minimum detection limit, allowing measurement of small doses as low as 0.03 mSv. They provide increased accuracy over film dosimeters.
Storing and manufacturing food materials like grain can be extremely challenging. Even the slightest bit of extra humidity can create mould growth, causing the grain to deteriorate. This leads to economic losses for manufacturers in the commercial food industry.

2014 Conference on Monitoring and Surveillance of Asbestos-Related Diseases.
With millions of square meters of materials containing asbestos still in place in buildings and industrial equipment, the risk of asbestos exposure remains and will persist for several decades. Approximately nine hundred thousand workers are potentially exposed to asbestos in the French construction sector. According to the conclusions of The French National Mesothelioma Surveillance Program (PNSM) published in two thousand and eleven: Occupations most at risk are: Plumbers, pipefitters, sheet metal workers boilermakers, electricians, welders and flame cutters installationIn two thousand and ten: almost one hundred and sixty thousand workers of the general scheme of Social Security occupying “plumbing-heating activities”: eighty-five % of occupational diseases related to asbestos. But paradoxically: Few exposure data are available for these workers. This can be explained by: Size and dispersion of the majority of concerned enterprises, occasional and short-term exposure, duration of difficult samples, logistical constraints linked to conventional sampling method. To overcome these difficulties the lack of exposure data, INRS decided to investigate an alternative to conventional sampling.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. According to the provisions of the
Radiological Safety Norms in
Interventional Radiology and
Radiology Practices (NSR-11), the
authorization holder should keep a
record of the radiation field
measurements in the controlled areas
and the adjacent areas of the
Controlled Areas for the Points of
Interest specified in the authorization.
The measurement points are set by
CNCAN in the authorization process.
The frequency of measurements is
usually 3 months in the case of dental
x-ray, mammography and
osteodensitometry being 6 months.
3. Dosimetric monitoring of the work environment includes:
-Monthly dispatch of dosimeters before the 1st day of the
month
-Interpretation of thermoluminescent signal, evaluation
and reporting H * (10). Availability of results: 2 - 5
working days after receipt of the dosimeters worn
through the on-line database - RepDoz
- Issuing dosimetric bulletins
- -Account online to tracking results and viewing history
Advantages of using thermoluminescent dosimeters:
- -Modern Technologi which is very sensible
4.
5. • The modern technology, used in most European
dosimetry laboratories individual. Thermoluminescent
dosimeters are currently used in most EU countries for
individual dosimetry monitoring.
• The detectors are made of tissue-equivalent material:
the thermoluminescent crystals used (Li2B4O7) have
Zefectiv close to human tissue which leads to a significant
improvement in personal equivalent dose ratings.
Detector type: - 2 elements: Li2B4O7: With phosphorus
equivalent tissue; - 2 CaSO4 elements: Tm phosphorus
with great sensitivity Ease of use of dosimeters:
• Thermoluminescent dosimeters represent a unitary
system, composed of 4 thermoluminescent crystals
embedded in a special cassette
• There is no need to exchange the box: at the end of each
month, the exposed person professionally handles the
dosimetre worn and takes over the new dosimeter ready for
wearing.
6.
7. Very low dose values can be determined: minimum detection limit of the system the
thermoluminescent is much lower (by 40 - 70%, depending on the field of use) than
that of the film dosimeter. There is a possibility of very small doses, starting at 0.03
mSv, leads to a reduction in cumulative doses over one year. Increased accuracy of
measured measurements due to energy dependence much more (up to 20% for
thermoluminescent dosimeters, compared to about 2000% for film dosimeters)
8.
9. Different colors are used for consecutive months: Thermoluminescent
dosimeters are sealed in special bags, glued on a label with the name of the
person professionally exposed and the unique identifier of the dosimeter.
Elimination of the risk of contamination of dosimeters: sealing dosimeters leads to
avoidance of contamination with various radioactive substances (in the case of
nuclear medicine laboratories or research laboratories), dust, chemicals, etc.
