These various radiation meters were originally procured and/or used by the NSW government agencies including the former State Pollution Control Commission (SPCC), the Environment Protection Authority (EPA), the NSW Department of Environment and Conservation (DEC), and possibly the NSW Department of Health. These agencies, collectively over the years regulated the use of radiation apparatus (for example x-ray machines used in medical diagnostics) and radioactive substances (for example cobalt-60 used in industrial gauging applications).

The equipment was used to measure the type and intensity of radiation and it exemplifies one of the many aspects of regulation administered by government health departments and augments the Museum's collection of measuring instruments and workplace health and safety material.

Radcal is the recognized leader in radiation and invasive measurements for medical X-ray Quality Assurance, X-ray test and X-ray compliance. Other applications include, but are not limited to industrial X-ray and nuclear power ionizing radiation measurements. Radcal's reputation had it's beginnings in 1975 with the introduction of the MDH 1015. The 1015 was designed for the FDA as an easy-to-use, reliable and accurate radiation measurement instrument.

Radiation monitor, 'Model 9010 Radiation Monitor', metal / plastic, made by Radcal Corporation, Monrovia, California, United States of America, 1997-2005

This detector is used by hospitals and other health organisations to make routine or unscheduled service of x-ray machines. It is contained in a hard black case that contains 5 probe attachments as well as the control unit. The control unit displays measurement results and menu selections on a liquid crystal display. The main user controls are the SELECT dial and the ENTER push button located on the face of the unit. The probes are grey boxes with different head attachments.

Radcal's Model 9010 is a radiation-monitoring instrument that can utilize a wide range of Radcal ion chambers. Typical applications include direct beam measurements for diagnostic x-ray, mammography, and fluoroscopy, as well as gamma radiation fields.
