Exposure Pathway meaning

Published by a LexisNexis Energy expert
What does Exposure Pathway mean?
An exposure pathway is the route by which ionising radiation or radionuclides move from a source to a human receptor (such as a worker or member of the public), resulting in a potential radiation dose. Typical pathways include inhalation of airborne radionuclides, ingestion of contaminated food or water, external irradiation from deposited contamination or sources, and immersion in contaminated air or water. In legal practice the term is used in radiation protection, environmental permitting and contaminated land risk assessment to structure the source–pathway–receptor linkage, quantify dose, and identify controls. It is a descriptive expression rather than a defined statutory term, although “pathway” is recognised in contaminated land statutory guidance under Part 2A of the Environmental Protection Act 1990 and is widely used in regulator guidance under the Ionising Radiations Regulations 2017 (IRR17), the Radiation (Emergency Preparedness and Public Information) Regulations 2019 (REPPIR), and radioactive substances regulation. Usage is broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland. Identifying exposure pathways is central to ALARP/ALARA demonstrations, setting and justifying discharge limits, emergency planning and food-chain restrictions, remediation and planning decisions, and proving or contesting causation in civil claims. Control measures typically aim to break the pathway or reduce exposure (e.g. containment,...

PRA to introduce 10-day accelerated pathway for catastrophe bond ISPVs and expand UK ILS regime, aligned with Solvency II reforms effective 31 December 2024

ISPVs enable insurers to reduce their exposure to significant events, including natural catastrophes, by passing risk to private investors via catastrophe bonds, or 'cat bonds'. Shoib Khan, the central bank’s Prudential Regulation Authority (PRA) director for insurance supervision, said the PRA will outline later this year how it plans to shorten approval times for submitted cat bond applications to ten working days, down from the current four to six weeks. Speaking at the Bank of America Securities Annual Financials CEO Conference, Khan added that the PRA intends to consult later this year on creating a new, accelerated pathway for catastrophe bond applications...

Fixed Recoverable Costs reforms: tracker and practitioner guidance on CPR 45/PD 45, fast and intermediate tracks, NIHL, consultations and timelines (England and Wales)

Fixed recoverable costs (FRC) Fixed recoverable costs (FRC) set out the sums recoverable from the paying party in litigation, introduced to promote clarity and proportionality in legal spend and process. The intention is that would-be litigants are not deterred by the risk of adverse costs exposure. FRC are now routine across several litigation spheres, though they are not universally applicable in every claim. As the landscape continues to change, this tracker seeks to chart the major milestones in the reform of FRC and offer granular guidance on particular stages and phases. CPR provisions on fixed costs For an overview of the present fixed costs rules and a pathway to related materials and analysis, see: Fixed costs (position on or after 1 October 2023)—checklist.

UK ILS and ISPVs: PRA authorisation and prudential rules, RAO insurance risk transformation, RTR offer/PCC regime and tax; 2024–2025 PRA reforms (accelerated pathway, SM&CR, LRC/FFAAT, AMRE)

This Practice Note sets out the UK regime for insurance-linked securities (ILS). It outlines what ILS are and identifies the requirements under: the Prudential Regulatory Authority (PRA) Rulebook for Insurance Special Purpose Vehicles (ISPVs); Section 284 of the Financial Services and Markets Act 2000 (FSMA 2000); the Financial Services and Markets Act 2000 (Regulated Activities) Order 2001, SI 2001/544 (RAO); the Risk Transformation Regulations 2017, SI 2017/1212 (RTRs); and the Risk Transformation (Tax) Regulations 2017, SI 2017/1271 (RTRs Tax). What are insurance-linked securities? ILS are a risk management tool for insurance and reinsurance firms. Insurers typically address their exposure by entering into arrangements where: the insurer keeps its direct liability to its policy holders; and another firm receives sums corresponding to part of the premium paid by policy holders to the insurer; and is obliged to pay amounts to the insurer that match an agreed share of losses suffered by...

PRECEDENTS
Insurance Condition Precedent: Net Zero Transition Plan for Climate-Related Liability Cover (Commercial Insureds)

Condition to Liability Cover for Climate-Related Claims This clause sets a precondition for insurance cover, compelling the insured to establish a rigorous net-zero transition plan before cover incepts for climate-related liability claims. A commercial policyholder must have such a robust plan (including emissions reduction targets) in place at policy inception, as a prerequisite to accessing liability insurance for climate-related claims. The objective is to encourage good behaviour, place the insured on a pathway towards net zero, and lower the likelihood of climate-related claims being brought against the insured, thereby supporting the insurer’s sustainable business. In short, it promotes better conduct, aligns strategy with net-zero goals and mitigates exposure to climate-related liabilities. The clause was created by The Chancery Lane Project (TCLP) under the title ‘Condition to Liability Cover for Climate-Related Claims’ and is referenced on TCLP’s website below. For detailed guidance on liability cover for climate-related claims, please consult the clause issued by TCLP. TCLP is the code name for the focused and collaborative effort of lawyers from around...
