Public Disclosure Protocol
1. reporting on its website within 48 hours of unusual operational events
2. posting environmental monitoring results,
3. maintaining two-way communication channels with the target audience,
4. and consulting with stakeholders to determine the type of information sharing that is requested by the community.
In addition to environmental monitoring, BWTX is also required to estimate the total radiation dose to members of the public resulting from its operations. The effective dose is used to assess the potential for long term effects and is calculated in milliseverts. It takes into account the absorbed dose, the relative harm level of the radiation, and the sensitivity of the human body to radiation.
[bmtextbox type=”warning”]The Canadian Radiation Protection Regulations set the effective dose limit for the public at 1 mSv. [/bmtextbox]
[bmtextbox type=”alert”]At the Toronto BWTX facility, the total estimated radiation dose to a member of the public is 0.017 mSv, approximately 1.8% of the public dose limit.[/bmtextbox]
