dc.description.abstract This paper presents an algorithm to calculate gamma dose rates intended for virtual reality (VR) applications. It dynamically adapts the method to cope with both accuracy and time requirements. Given the real-time constraints imposed by VR applications, more accurate, but computationally intensive stochastic algorithms (e.g., Monte Carlo) are not suited to this task. On the opposite end, a Point Kernel (PK) method can be effective in some cases with as little as one point (mono PK) to define a source, in contrast with the millions of points that Monte Carlo computes. Simple mono PK codes may lack the desired accuracy in some circumstances, requiring a more detailed source representation. In this work, a novel method is presented which automatically estimates the appropriate level of detail for a source's volumetric representation, then generates a non-regular mesh model and subsequently computes the dose rate via a PK method, performing this three-step process in real time. es_ES
