Fluence-to-Dose Conversion Coefficients for Muons and Pions Calculated Based on ICRP Publication 103 Using the PHITS Code

The fluence to effective-dose and organ-absorbed-dose conversion coefficients for charged pions and muons were calculated based on the instructions given in ICRP Publication 103. For the calculation, the particle motions in the ICRP/ICRU adult reference computational phantoms were simulated using the PHITS code for four idealized irradiation geometries as well as those closely representing the ...

Neuronal activities related to thermoregulation.

The hypothalamic thermoregulatory center was regarded as a black box some 20 years ago. Subsequent microelectrode exploration revealed the existence of two kinds of thermosensitive neurons in this area. Discharges of these neurons are now recorded not only from anesthetized animals but also from tissue explants, tissue slices, and unanesthetized animals as well. Neuronal responses produced by s...

Attempted validation of ICRP 30 and ICRP 66 respiratory models.

The validation of human biological models for inhaled radionuclides is nearly impossible. Requirements for validation are: (1) the measurement of the relevant human tissue data and (2) valid exposure measurements over the interval known to apply to tissue uptake. Two lung models, ICRP 30(1) and ICRP 66(2), are widely used to estimate lung doses following acute occupational or environmental expo...

Erratum to: Effective dose to adult patients from 338 radiopharmaceuticals estimated using ICRP biokinetic data, ICRP/ICRU computational reference phantoms and ICRP 2007 tissue weighting factors

1. For 79 % of the radiopharmaceuticals, the new calculations gave a lower effective dose per unit administered activity than earlier estimated.” Should be “For 63 % of the radiopharmaceuticals, the new calculations gave a lower effective dose per unit administered activity than earlier estimated.” 2. “As a mean for all radiopharmaceuticals, the effective dose was 25 % lower.” Should be“As a me...
