- reflecting legal provisions that have not been accurately implemented, or also reflecting newly amended legal provisions in the amendment to the Atomic Energy Act;
- adjustment of the calculation of derived limits for radiation workers;
- individual adjustments in the categorisation of sources of ionizing radiation;
- adjustment of the regulation of acceptance tests, long-term stability tests and operational stability tests;
- individual adjustments of the rules of record-keeping of sources of ionising radiation by the licence holder and the registrant;
- in connection with statutory authorisation, the stipulation of an excessive number of workplaces where a supervising entity carries out continual supervision;
- changes to the entry of persons into controlled and monitored zones;

- new provisions on notification to SONS of the submission of an application for authorisation of a clinical trial of
radiopharmaceuticals;
- new provisions on the details of regulation of radiological events;
- clarification of certain rules in relation to natural sources of ionising radiation and in the context of existing exposure situations;
- regulation of the consumption and distribution of locally produced or unprotected foodstuffs in areas affected by a radiation accident and the distribution and marketing of products located in areas affected by a radiation accident;
